iGEM Advisors Meeting
 +
5/1/12
 +
 +
Announcements
 +
Courtney: $500 is needed for travel funds because of a new fee that requires $25 per ticket, in addition to the ticket price. We will continue looking at departments and companies for funding, but all meetings to request funding should be set up with Courtney present. We should also contact companies in research park (Adi will take the lead on this). Our goal is to recruit $10,000 from various departments and companies in order to be financially secure this year and set up next year’s team. Adi will contact the ACES department (through Bhalerao) and Steven Sliger of MCB.

Agenda
 +
Wetlab Summer Plans
 +
PUF
 +
Make multiple PUF biobricks out of existing PUM1 genes and PUM1+endonuclease domain (provided by Dr. Wang at UNC)
 +
3 ways to test is PUF really binds with the construct
 +
Path 1: Put PUF binding site between the RBS and YFP. If no YFP is detected then PUF has successfully bound. We can also test various PUF binding sites: before the RBS, after the YFP, try using multiple PUF binding sites before the RBS
 +
Suggestion: put the endonuclease site inbetween the RBS and YFP so that when PUF binds we separate the RBS from the reading frame.
 +
Controls: In the positive control, put a PUF binding site, but don’t express PUF. That way we can see that the PUF binding site doesn’t disrupt the YFP expression on it’s own.
 +
Recommendation: This is the immediate and primary focus.
 +
Path 2: PUF between RBS and LacI. If PUF binds then LacI is repressed. The LacI is controlling the YFP, so we now see a modular response to PUF binding. We can also test the different locations of the PUF binding site within this model.
 +
Path 3: UNC has an incomplete project working with a PUF library that recognizes certain genes. We would use the PUF with the endonuclease domain to cut the designated genes. The genes from this library can get made into biobricks.
 +
Details and illustrations of this plan are included in the handout (attached to the meeting minutes).
 +
How are we selling the PUF project? Why are we doing this? Why do people care?
 +
We are creating a research toolkit that uses PUF and linked proteins for translational repression.
 +
This is another technique used to make a gene circuit, but can also be further used in therapeutics, such as treating HIV of myotonic dystrophy.
 +
This puts us in the “new application” category.
 +
It is the hope that this ends up being more effective/faster/cheaper/specific, etc.
 +
We want to sell this project to the judges (both for iGEM and entrepreneurial).
 +
We need to find a current project so we have a specific, concrete example of an awesome application. This is key to market ourselves. We need to show that we have helped solve a problem because PUF was better than any other option available.
 +
1st step in the entrepreneurship project is to look at patents and trademarks for already existing methods of translational repression.
 +
We need to have a specific need and market to satisfy. Specific examples are key! Data is also good.
 +
Do the simple key wetlab parts of this project, and continually research applications during the summer.
 +
Resveratrol/Piceatannol
 +
Korean lab under Prof. Chul-Ho Yun is willing to share mutant strains with us, and the first author of the paper, Donghyun Kim, is a post-doc in the Kemper lab on campus. Cara is in communication with both the lab and the author
 +
ChemSketch is being used to draw derivatives of piceatannol and then calculate the logP value of that compound to find the solubility. Then use the Molecular operating environment software to model docking of these more soluble compounds into the insulin receptor. Then would turn at least one of the mutant strains (BM3) from the Korean lab into a biobrick.
 +
Resources: The school of Chemical sciences is being contacted about using their software, and the Hergenrother, Spies, Nair, and Cobb labs are also being contacted. 1-2 other iGEMmers will work with Cara on this project.
 +
Recommendations: In vitro production of piceatannol is expensive and time consuming (purify enzyme, etc). But if we pursue a fermentation, we can produce large amounts of piceatannol, which is a very good application and great for our entrepreneurship competition. We could even produce our own reseveratrol to feed into the piceatannol fermentation. Potential problem: can we secrete piceatannol?
 +
Discussion
 +
The PUF project is technique based and the piceatannol project is application based. It’s great that we have both of them and they should be pursued in tandem.
 +
Proposed budget: asking for $21,000 in materials and supplies, but we can get many free supplies.
 +
Don’t worry about money, if we come up with a good wetlab project, then it becomes easier to obtain funding to travel to the actual competition.
 +
We have enough money to do both projects in tandem.
 +
Call Amanda about GeneArt. We may have money to use up with them. 
 +
If we check with Courtney before purchasing anything, we should be fine with money.
 +
Once we start doing work, it’s easier to get funding. This is the big idea.
 +
Our budget this year is actually bigger than normal, so as long as we work hard and are responsible, everything should work out.
 +
 +

Thursday, 7/5/12
 +
- Adi, corporate/entrepreneurship - Been working with Alex on the entrepreneurship wiki, went to Chicago to do design the website with Alex. At this point have the entire structure of the wiki, but are hosting it on a different domain so that the code can get perfected and then uploaded to the iGEM wiki. So far, it looks so good. The iGEM entrepreneurship wiki should be up in around 2 weeks. Once there is data it will get uploaded and the entrepreneurship code can get transferred to the normal wiki if necessary. Also, obtain $250 from the Roy J. Carver Biotechnology Center, Courtney has given the approval to use this to buy enzymes. SARSTEDT is also going to sponsor us, but they have not specified an amount yet.
 +
- Anthony, PUF biobricking - looked at gel of PSB1C3 run by Asha. The bands were not correct, so digested more. Each had 2 bands and none of them were the right size. Will use linearized plasmid next. Made LB and autoclaved more 1.5 centrifuge tubes.
 +
- Asha, PUF - still waiting on WT PUF/ pBAD primers, so in the meantime I made 11 tubes of DH5a cells. And plated YFP constructs from glycerol stock to do colony PCR again.

Friday, 7/6/12
 +
- Adi, Entrepreneurship - same as yesterday. entrepreneurship wiki, money from Roy J. Carver (for sequencing), some sort of sponsorship from sarstedt. DWR and Fisher haven’t really responded, so Courtney will contact them personally to try to get a response. Will contact Ginkgo Bioworks next. Will also set up times outside of advisor’s meetings to meet with Joe Bradley.
 +
- Anthony, PUF - PCRed 2 tubes of WT PUF, started 3 ligations with 3 different digestions and the one type of PSB1C3 that kind of worked. After the biobricking, will help Angela and Asha with the PUF and pBAD.
 +
- Isiah, Washington characterization - Don’t have to wait for alkanes, so on Monday when Divya returns they will start the media growth along with the K12 and Petrobrick. Ideally by the end of the week alkanes should be produced and that fact means the petrobrick was successfully characterized. Need filters for 500 mL of liquid. Actually would be ideal to start media growth earlier, so will talk to Divya about that. Courtney has trained Isiah on how to order things, so when she leaves we will order things through Isiah (Courtney will still approve purchases remotely).
 +
- Asha, PUF - Did colony PCR on the YFP constructs, PCRed WT PUF for pBAD, ran the gel for both and saw primer dimers for all. Must redo. Using the right primers? Reused the old YFP primers as check primers, which should work but might not. Will look for the check primers. Human practices: get mike from the Art department (connected to the museum) open from 11-5 during the summer (go to the second floor and talk to them).
 +
- Uros, RNA scaffolding - continued work on split GFP. Had to redo a gel so ran the digestion for 4 hours (an extra hour from last time). Did a gel on it, and will continue ligation. The split GFP should be done and sent out for sequencing on Tuesday. Next Friday is the goal for tethering the split GFP to PUF. thinking about characterizing the scaffold, but putting that off until the split GFP is done. Will need assistance with characterizing the split GFP and scaffold. Will characterize the scaffold by RTPCR (being trained currently). Will consult Pam Silver paper on how they did it (think they did microscopy, but that might not be the best option for us).
 +
- Angela - We are on track according to the 2012 iGEM judging form: characterization (gold), human practices (gold), working on biobricking and characterization of PUF (silver). The sequencing and characterization of PUF will happen in parallel to save time. A deadline for finishing characterization is next Friday (7/13). That way by the end of July we will be meeting all the qualifications for the gold medal. This is a very strict deadline because we have less than 2 months left to do lab work. The regional jamboree is the first week of October, and September is completely dedicated to perfecting the poster and presentation. We are running out of time, so everyone needs to work as hard as possible. Angela, Asha, and Anthony are all working on the same PUF plan to try to finish the PUF and YFP cloning done by Monday. Then we can begin the characterization and hopefully finish that by Friday.

Monday, 7/9/12
 +
- Adi - meeting with Joe this week to look over entrepreneurship executive summary, are being sponsored by SARSTEDT (box of supplies came today), emailed thank yous to sarstedt and gold biotech. Should contact Octochem about further sponsorship.
 +
- Divya, Washington characterization - did the M9 media for alkane production, for publicity is writing an email to IMSA, Asha took pics for blog, Divya will email Flickr password out. Will talk to Isiah about tshirts. After actually obtaining alkanes, will write up the characterization with isiah. Followed a bunch of people on twitter (37), and currently have 20 followers. Also need to make a new trifold for Quad day and E-night. Add any other publicity ideas to the google doc.
 +
- Cara, PHAT - have designed sequencing primers but not ordered them yet (wants to try using VR and VF), might need to design another set of sequencing primers to account for 100 bp mess up at the start of every sequence. UPenn is going to ship genetic info on rotobacter at sometime next week because the rotobacter from Dr. Metcalf isn’t working. Is talking to someone in MMG about high performance thin plate chromatography. Have glycerol stocks of BM3s in expression vector. Get things characterized before biobricking (plus, biobricking primers aren’t in right now). Would like to buy malonyl-CoA for $80, but haven’t talked to Courtney about it yet.
 +
- Bob, webmaster - redoing PCR for 4CL:STS and will run gel later, wiki will be changed so that the lab notebook is separated among the PUF and PHAT projects. Have bullet points and pictures, doesn’t need to be very intense. Keep it simple and clear. Each day has a data section with numbers or pictures divided into the PUF and PHAT projects. Can also have tabs and drop down menus. Also uploaded most recent minutes. Will also add Sarstedt to the sponsors page.
 +
- Anthony, PUF - did all steps from PCR to transformation of WT PUF. The transformation didnt work so have started redoing it.
 +
- Asha, PUF - working on re-doing the eYFP in protet constructs (both the control binding site and the PUF binding site.) Did PCR today, and needs to run the gel later. Then will religate, transform, grow, do colony PCR, send to sequencing and begin characterization. Eventually, will clone in the WT PUF in pBAD to the cells. Also making plate (10 LB, 25 Amp, 25 Amp and Cm) and making more pBAD. Will contact local science camps about presentations/assisting in lab for outreach.
 +
- Angela - after doing digestion, you don’t always have to do gel purification, can just do PCR cleanup. Because alot of these runs are low copy number, so gel purification yields low numbers. Did tons of PCR for PUF and most worked. No pBAD worked in the digestion, so got more pBAD from Asha and will hopefully have finished digestion/ligation/transformation by tomorrow. Will then send in for sequencing.
 +
- Uros - trying to get the pETDUET to work with split GFP, but hasn’t really worked. the pETDUET plasmid is low copy number and so we have low yield and have a really faint band with split GFP. If we sent the split GFP tethered to PUF to sequencing on Friday, we would get it at the end of July. It’s expensive and takes a while but we know that we would have it. If we did it by ourselves it would be difficult, and take an undetermined amount of time.

Tuesday, 7/10/12
 +
- Divya, washington characterization - still waiting for the stuff to grow, will email Isiah about further updates, need to talk to Jin about GCMS on Thursday. helped Asha plate some stuff, will make plates tomorrow.
 +
- Anthony - looked a PCR gel. only 1 of 3 worked, but it was a lot of yield, so it will last a couple of rounds of digestion/ligation. So the digest/ligate will occur today and be finished tomorrow.
 +
- Asha -YFP PCR worked. looked at other YFP colonies under UV light and none of them glowed =( so it’s a good thing we’re re-ligating! ruined 70 plates... sorry! =(
 +
- Angela - did ligation/transformation and will see if it worked later tonight. designing primers for primer extension (backup plan). Being trained in Rao’s lab to use sewing and use the florescent meter to measure the mcherry and venus for the reporter genes. Asking to be trained for mathematical modeling for the output of our project.
 +
- Uros, scaffold and tethering - working to tether PUF and GFP. Read the UNC paper (draft) on how they tethered, but will need more info because there is no supplemental info or data. Also need to send some emails out and continue reading up on it. Wants to talk to Todd about tethering and the low copy plasmid. Ligations didnt work and transformations didnt work =(

Wednesday, 7/11/12
 +
- Asha, PUF - yesterday digested eYFP and protet and got bands of the correct length. Ran ligation for 7 hours using a 10:1 ratio of insert:vector. Transformed today, Bob and Cara plated for me. Will look at plates tomorrow. If colonies, will look at them under the UV light to see if they glow!
 +
- Divya, made CM, Amp, and Amp+CM plates for Asha, talked to Jin about GCSM: work with Quan Lee (?), Isiah will pick up alkane production tonight, will resuspend tomorrow in EtOAc to extract
 +
-Bob, put Starssted on the sponsor’s section, and worked
 +
-Angela:
 +
Constructed primers using primer extension method for the entire PUF project constructs. Primers for cloning of YFP to ProTet and wild type PUF to pBAD. To be more precise the method is termed CPCA used for cloning. The benefits are that it doesn’t need any ligation or gel purification. Once the primers arrive, probably Friday, we can try the PCR and check whether the insert is present or not by check primers. Check primers were ordered today as well. Wild type PUF need another set of sequencing primers. Orders have actually not been placed yet, it depends on Courtney. CPAC method doesn’t leave any scars in the cloning and no gel purification is required, only PCR and gel running is required. Perhaps the method will be taught sometime later in the week to the whole group. One modification is that instead of using E0030, Venus will be used. PSB1C3 will be arriving on Friday. Transformation after ligation was done today, colonies will be seen tomorrow. Starting another set of regular cloning in case CPAC doesn’t work, from digestion/ligation/transformation.
 +
-Adi:
 +
Alex will be arriving this weekend. The entrepreneurship wiki should be done in approximately 2 weeks. Adi will e-mail Mark from Octochem about a chemical needed for the PHAT project.
 +
-Anthony:
 +
Digested, extracted, and ligated PCR of pBAD and wild type PUF PCR. Transformed today and will plate, hopefully there will be colonies tomorrow.
 +
-Uros:
 +
Continued to investigate how to tether PUF to a correct split-GFP sequence. Asked Angela for further information on the UNC paper in order to receive more information where on PUF was the tether placed. Proceeded to e-mail the graduate student who helped collaborate and give advice for the RNA Scaffold synthesis about the split-GFP sequence used in the paper (Pam Silver paper). E-mailed Dr. Bourde, the principal investigator of the lab which was referenced in the Pam Silver paper, concerning split-GFP work for either the sequence or possible part shipment. E-mailed Todd in order to get more information or suggestions on where to head with the tethering project. Also, Todd might offer insight whether it is still feasible to produce the construct ourselves before August and so we could save money before synthesis. Been trying to find a trustworthy source for the split-GFP sequence and have found two sources. One of them being from a past iGEM team and the other from a research article. For Friday an update will be presented to the advisors along with a list of options which can be pursued, one of which will be decided upon collectively. An e-mail was forwarded from Courtney, sent by IDT, that the RNA scaffold gene is still in production and everything is being done so it could be properly made. Any other product ordered along with the scaffold should be asked to be sent immediately due to the unpredictable completion time of it.
 +
-Cara/Bob:
 +
Cara and Bob made smaller aliquots of freshly made LB media and put them into the 50mL conical tubes. The contents of the conical tubes should be transferred into small glass containers and the tubes autoclaved/reused. Gloves arrived today, needed materials need to be updated and immediately communicated to Courtney. Rafferdy got back to Cara and has TLC plates for her to use. TLC standards worked yesterday, solvent used was 85:15:3 chloroform, methanol, acetic acid. Reverse phase was tried as well. 10mL of solvent was used, 250mL of solvent was made which should last a while. All reagents were received from MMG. Gels were ran to check whether PCR worked last night, PCR might have worked. The gels need to be extracted and sequenced in order to check whether it worked. IDT will be e-mailed/called to separate the orders of scaffold and primers due to delay of the scaffold production. 5mg of piceattanol and 100mg of resveratrol are in the inventory. All piceattanol contents were resuspended in ethanol. Resveratrol will be diluted as well in some solvent. Starting fermentation is the next step. Bob plated some things for Asha after transformation. Sponsors were also added to the Wiki and the lab notebook section was updated. Meeting with Melissa will be held by the end of the week. WashU credited UIUC coding done by Bob for the Wiki!!

Thursday, 7/12/12
 +
- Divya - Isiah got the cultures out. Talked to Jin and it turns out that we actually need to wait until the alkanes arrive to use them as a standard for GCMS. Talked to the GCMS lady about conditions. Divya will look up the info and email it to the lady to create the standard curve. Either tomorrow or monday results will occur. On next Monday, will begin helping with cloning.
 +
- Asha - transformation of YFP ligation didn’t work, so replated. Also another ligation with only a 5:1 insert:vector ratio. Also went to the art department to ask about filming equipment for human practices. The checkout counter wasn’t open, but got an email to contact.
 +
- Anthony - failed transformation from yesterday so replated. Also transformed again with a different ligation. Among 4 plates hopefully there will be results! =)
 +
- Bob - ran a gel of Cara’s PHAT optimized PCR. Started a digestion of it. Working on wiki, more specifically putting all of the lab notes from the google doc on the wiki in nice little tables. Will also contact Melissa.
 +
- Cara - did gel purification of the PHAT optimized PCR. The band is not the right length, but the PCR has consistently yielded this band. Therefore purified it and wants to find what it is. The suspicion is that the primers and PCR are working and the part is messed up. Digesting the vector or sequencing the part are good things to do at this point. Will type up a protocol from Brad and send it to everyone about growing things in a controlled environment for PHAT.
 +
- Uros - talked to Todd in detail about the tethered PUF to CFP construct ourselves. He thinks that we can do it ourselves and complete it before August. The plan involves making alot of primers (angela will help). In parallel will construct a plasmid with the CFP parts so that we can have a control to see how the CFP works. have to check if CFP is in the kit and if we can just PCR it. Still the debate: do we synthesize or do it ourselves? it’s the problem of time and money. will sit down and create a very detailed plan with Todd tomorrow.
 +
- Adi - been working on the wiki, Alex will come down on Saturday and everyone should come to lunch to meet him and discuss

- Angela - everyone needs to create a powerpoint of work and data to present at the advisor’s meeting tomorrow. Having problems with comp cells because transformations aren’t working. So is going to take some iGEM comp cells and try the same ligation transformations. It that doesn’t work will then transform with boughten comp cells. Prepared more ligations so will continuously ligate and transform until results. Finished the primers for primer extension and checked with Kori about making a standard protocol. Next week the primers will arrive and will start cloning the modular PUF reporters via primer extension.

Tuesday, 7/17/12
 +
- Uros - By tonight will have a google doc up of his plan for the primers for the tethering and making the split CFP construct (in parallel). There was a mistake in one of the primers, but he caught it. Received an email back about split GFP, and got referred to another person. Will email her tonight and hopefully will get a sequence. If cloning/tethering doesn’t work by Monday, will send out constructs for sythesis.
 +
- Anthony - still working on putting WT PUF in pBAD. Ran a gel and extracted from yesterday’s digests. There’s no band for pBAD. So starting 3 new digestions from different minipreps of pBAD. Hopefully will get some result from that, because can’t start ligation until the pBAd digest works.
 +
- Asha - old plates of YFP constructs had weird growth 4 days. Uros and I looked at them and didnt think that they were fluorescing. Working on a positive and negative control to look at fluorescence. Negative will DH5a and positive will be E0030 subcloned into ptet (working with Angela on that.)
 +
- Divya - working on biobricking WT PUF. PCRed more WT PUF. Isiah will run the gel on them tonight. Also poured Amp and CM plates (10 of each). Still waiting for the alkanes to arrive, so the Washington characterization is delayed. Isiah will call the company to see what is taking so long.

- Uros - no meeting yesterday because Uros and Angela discussed the format of the daily meeting. A big reason why the meetings run so late is because people are late. JUST BE PUNCTUAL! If you have a legit reason for being late, text everyone to let them know. If you miss a meeting look at this google doc to look at everyone else’s work and also be sure to update the google doc for the lab notebook. Come in tomorrow with a brief checklist of your project goals for the end of the summer so that everyone can be updated and be ready to start participating in quality discussions about all the separate projects. The google doc on which to share these summaries has been shared with everyone.
 +
- Uros - trying to make a split CFP construct, trying to clone the 2 parts (C and N terminus) into the plasmid. The Cterminus part worked today for PCR. Need help with this part tomorrow. Adi and whoever else needs to be in lab tomorrow at 9 to help out. Uros will send out a thorough google doc of instructions. Made a final draft for the WT PUF alpha g for sythesis. Upon advice of a post doc made a draft for WT PUF and the split GFP tethering.
 +
- Divya - PCR of WT PUF yesterday. Isiah ran the gel. That PCR procedure worked. Another PCR today was performed by Isiah according to a diff procedure. The gel was run by Divya and the PCR failed.
 +
- Anthony - transformed and plated yesterday’s ligation, started another ligation in case those don’t work.
 +
- Angela - negative control for YFP is cloned, YFP construct is completed, sequenced and it fluoresced. Successfully used primer extension to clone Venus YFP into protet. Instead of using the biobrick E0030, we will use Venus from now on. Now we will be able to start looking at our designed RBS to see if it works. Will get primers on Tuesday or Wednesday. Takes 2 days to clone via primer extension.
 +
- Bob - been helping several people out on all of the projects, but his main efforts are for the PHAT project. Wiki design question: for the lab notebook, we are split into the PUF notebook and the PHAT notebook. the PHAT section is structured in a continuous page where the tab buttons jump you to a different location on the page. The PUF section is structured so that every tab has a different page. Which format is preferred?
 +
- Cara - PCR that Bob performed yesterday was run on a gel. Think it worked, but the ladder wasn’t really clear, so the digestions are being run with lots of controls. Will also soon be able to see if the BM3 site was accurately mutated to get rid of the PstI site. Do we need primers to send it out for sequencing? . Has the 2 primers for the outside of the 4CL:STS insert, but needs primers for the inside of it. Perhaps a colony pcr would be best. Use VF and VR2 standard primers. However, need to transform and plate to get the colonies necessary for that (have been working from liquid cultures so far.) Will also make IPTG.
 +
- Adi, Entrepreneurship - talked to Joe and Alex about continued wiki design. First image will be the photo of our team, then it will slide by to be a video of the elevator pitch. Doesn’t want it to be a video of people, but more of an animation or a pretzi-like thing. Will have voice try-outs in collab with human practices video. Is compiling a new list of supplies.
 +
- Asha - gonna move on to cloning wtPUF to PBAD30 with Anthony. Human practices is going to do filming soon. Need microphone. Anthony has a professional recorder.

- no advisor’s meeting
 +
- Meetings have been moved - they will only be on Monday, Wednesday, and Friday. On Fridays that we have advisor’s meeting, we will not have a separate meeting but instead wrap up for a few minutes after the advisor’s meeting.
 +
- For future gels, or really nice gels that we want to take good picture of, don’t use the big UV tray next to the computer.
 +
- Angela - YFP (Venus) fluorescence! Also, it’s sequence has been confirmed.
 +
- Divya - did PCR and will run gel later.
 +
- Asha - PCRed more WT PUF for pBAD.
 +
- Isiah - working on digestion of linear PSB1C3. Will later run a gel.
 +
- Adi - miniprepped petduet and the K---- biobrick part (NCFP and CCFP).
 +
- Cara - Waiting on the digest for more conclusive results
 +
- Uros - tethering is delayed because a delay on one primer and no sequence of mutant PUF.

Wednesday, 7/25/12
 +
- Angela - no colonies on PUF eYFP construct. Needs minipreps of puf, pbad, ptet, everything. Did a 4th ligation and will hopefully see colonies. the backup is synthesis, will speak with Dr. Jin about it. Credits! We can get credits for this research, but need to check with the individual advisors in your home department. An evaluation has to be done after the summer, but should really been done in the first 2 weeks of the semester. Will probably get 2-4 hours. Need to get going on biobricking and characterizing!
 +
- Asha, human practices - will hold interviews with Dr. Mumm and Dr. Below for the transgenic plants video. Will also refine the media research from the beginning of the summer to create a database. Still trying to trouble shoot pBAD problems. Will digest minipreps from inoculation tomorrow and will use butanol precipitation on ligation on Friday morning.
 +
- Divya - met with Melissa and the IGB communications director Nick Vassi yesterday. Discussed creating a video and writing an article. Nick Vassi said that if we were to write an article, he would review it and send it to his contacts at the Daily Illini. For the video presentation, he said gather as much footage as possible. Will present this video for recruitment among bioe 120, eng 100, and las 199 classes. For high school presentations will use the human practices videos. Starting to think about contacting these high schools and classes. Change in the plan, Divya will focus on the Washington characterization, Isiah will do the PUF biobricking.
 +
- Anthony - transformations from heat shock didn’t work. Desalted and electroporated again and hopefully will see colonies tomorrow. Started another ligation just in case that doesn’t work. Also, everyone should be sure to put away all of their supplies.
 +
- Ligation troubles - is it reagents or the materials?
 +
- Bob - Continued a restart of the BM3 fermentations, now with a control that is not induced. Did colony PCR of 4CL:STS. Want to discuss it with Angela because don’t know how to interpret the results.
 +
- Cara - tried to make comp cells, but need an id and access code to run the big centrifuge and need to talk to brad about that. Will look into it and then make the comp cells as soon as possible. Last piceatannol synthesis, did something wrong. Might have overloaded the TLC plate and also had a weird substance left over from the speed vac. Will also try to further refine the protocol. Next step is to lyse the cells to see if the cells are creating picetannol, and just not exporting it. After that will need to try to purify the supernate to try to get some concentrated supernantent to run.
 +
- Uros - trying to tether PUF and CCFP. Yesterday tried to amplify the 2 parts but was only using forward and reverse primers (1 primer for each). This amplified PUF and kinda worked on CCFP. But it didn’t work for the actual tether. So tried again today just with the tether with HF buffer instead of GC buffer. Got primer dimers again. Ran it again on a gradient of 50-55-60-65, used less primers, lengthened annealing time. Will check the results of that later tonight. If this fails the next plan is to do PCR so that the PUF and the CCFP will have the restriction site and linker sequence on them even before tethering. Will be gone July 30-Aug. 6 and needs someone to help out with the RNA scaffold characterization. Will send out a google doc to everyone by next week. Waiting on Angela to get the mutant PUF sequence to get sent out for synthesis in case this doesn’t work.
 +
- social! Thursday night there is a rodeo at 7 at the county fair! It’s $5 to get in the door and Cara will post more info on the fb page. consider eating before because the food is expensive.

Monday, 7/30/12
 +
- Adi - needs to figure out how to pitch to companies with whatever data we have so far. Cara and Angela should send Adi a three sentence summary of preliminary work and data to convince companies to sponsor us. Do this by Thursday.
 +
- Bob - been working on the petDUET and CCFP stuff for Uros. The ligation was finished over the weekend, so transformed into DH5a today. Also the petDUET miniprep DNA has been yielding really low, so inoculated 16 mL to get a good supply.
 +
- Cara - will be focusing on her final on Wednesday. Will resume work on Thursday. Might be considering sequencing.
 +
- Asha - got colonies from last pBAD-wtPUF ligation, think it’s the nuclease free water. Gave to Angela for colony PCR. Made inoculation for glycerol stock of new, better pBAD. Had interview with Dr. Below, got 30 min of footage.
 +
- Anthony - started new digestions for pBAD-wtPUF.
 +
- Angela - no meeting on Friday. Used the new nuclease free water (which appears to be working well!) Have to order new primers for the PUF-binding YFP construct. Will be gone Wednesday, Thursday, and Friday. Barrier to ordering Uros’s tethers - doesn’t have the mutant sequence from Dr. Wong.
 +
- Divya - replated transformations of WT PUF biobrick, Isiah did a colony PCR that might have been successful but will redo it tomorrow. If it is confirmed, the PUF biobricking is complete. Will be continuing on with the Washington characterization tomorrow, talked to Jin’s lab about GCMS.

- Angela, PUF - sequencing results are not back yet. Perhaps the concentration was too low. Cotransformations have been performed and obtained colonies. The first protein test was inconclusive, but the colonies don’t fluoresce.... perhaps the YFP has become degraded. Ended up characterizing E0030 by mistake, because out of nowhere it works. Will be working on lac Z characterization as well.
 +
- Anthony, PUF - did a protein gel to analyze WT PUF expression. Under arabinose, it looks that there is not much expression. Transformed into BL21 to see if that works better. Will test DH5a once more, and if that yields the same result than the BL21 will be used. The problem could be the T7 promoter.
 +
- Arabinose problems - Angela researched LB and it’s very rich, probably has arabinose. So will need to use M9 instead because it won’t have arabinose.
 +
- Asha - completed all the interviews for human practices, will work with Divya to tie human practice to publicity. Will go home and edit videos like crazy =)
 +
- Divya - working on an article for the daily illini. Will be trying to coordinate a practice session that will also function as a seminar for critique. Will invite IGB, general public, and BioE department. Also, quad day!
 +
- Divya, characterization - ran a control of the GCMS today. Need to confirm that the controls worked. needs someone else to run the rest of the tests on the GCMS tomorrow. The tubes are all prepared and it’s really easy. It will take about an hour. Adi will take care of it.
 +
- Adi - is now updated with the PUF project, and now needs a PHAT project update. Needs them to work on the business plan.
 +
- Bob - has been helping out with Uros’s stuff. Needs to redo colony pcr. But doesn’t have a lot of colonies left on the original plate, so inoculated from the leftover colony and will replate and redo colony pcr.
 +
- Cara, PHAT - this week will finish PCR’s for TAL, is ready to send out 4CL:STS for sequencing (1.8 KB gene, has 5 sets of primers), has performed mutagenesis on BM3. Emphasis will be on thoroughly characterizing the BM3.

Friday, 8/24/12
 +
Asha - went to a conference on technical presentations, is creating the human practices video and powerpoints for outreach school visits
 +
Isiah - helped out with scaffold, ran a PCR that didn’t work very well, will throw out and make more media
 +
Anthony - been helping Angela with PUF constructs and running protein expression gels. Mutant PUF is working well and WT  PUF not so well.
 +
Bob - been working on restructuring the wiki alot, needs all the new/revised protocols,
 +
Uros - someone needs to throw out the contaminated stack of Amp plates in the 4 degree room and make new ones, been doing scaffold work, got successful transformations of the scaffold, but had problems with minipreps (DO NOT USE the p3 neutralization buffer), used a lot of micrograms but got a big smear, will try in vitro transcription tonight, if that works will move on to running gels
 +
Angela - have been testing with YFP but still need more results, cloning 8 more constructs so needs a lot of help (been recloning things alot as they don’t work), will send results directly to Bob to be posted on the wiki, cloning works because florescence is observed but still need to further quantify the functionality of PUF, still need help with the YFP testing and with cloning all the constructs
 +
Sept 3 deadlines - need to have the final draft of the abstract and the safety questions. For the abstract need a draft by Wed/Thurs to have at least one advisor look at it. For the safety questions need “institutional” approval of our safe practices.
 +
Quad day - Divya and Asha working on a new poster and handouts, maybe wearing labcoats? (good or bad idea... debate)

Friday, 8/31/12
 +
Should we all come together on one project or continue in these multiple tracks?
 +
- option 1: everyone comes together at the end to try and invest max time in PUF in order to produce results. Hopefully this not only yields results but will help team unity and bonding
 +
- option 2: everyone continues working on the side projects. perhaps all of them don’t get done, but there is also the opportunity to have more biobricks and more data. Everyone still had leadership and ownership over their own projects.
 +
- what will the judges like the most? typically they like 1 really complete and detailed project, and then a small side project or an idea that accompanies the other one.
 +
- PHAT: trying to biobrick 2 of the enzymes. After biobricking them, will work on characterizing them.
 +
- PUF: tested WT PUF with YFP. Whenever there is PUF present, YFP doesn’t glow. This answer has been affirmed 5 times. However, the control is also not glowing, but it shoudl be. Also did protein expression gels for WT PUF and mutant PUF. Found that mutant PUF has good expression, but WT PUF has little expression. Today did a mutant PUF test and found that the mutant PUF when applied to the PUF binding site YFP, did not bind. This shows the specificity of binding of the PUF molecule. Dr. Wong has also sent a help construct in order to reproduce his experiment. The construct consists of an engineered mutant PUF. It was inserted into BL21. The mutant PUF site specifically binds to LacZ. Our next steps are to transform the mutant PUF and he Lac Z testing construct to BL21. Biobricking: WT PUF and mutant PUF with plans to characterize both of these. Currently testing:
 +
- control YFP/wt puf YFP (protet)  with WT PUF (pBAD)
 +
- control YFP/wt puf YFP(protet) with mutant PUF (pBAD)
 +
-***control YFP/wt puf YFP (pBAD) with WT PUF (protet)
 +
-***control YFP/ wt puf YFP (pBAD) with mutant PUF (protet)
 +
-***control YFP/wt puf YFP (pBAD) with WT PUF (pet)
 +
-***control YFP/ wt puf YFP (pBAD) with mutant PUF (pet)
 +
- Lac Z (pBAD) with mutant PUF (pet)
 +
- Lac Z (pBAD) with WT PUF (pet)
 +
- RNA scaffold: characterizing the scaffold and wants to biobrick the scaffold as well. Will be characterizing the synthesized parts and also wants to biobrick the split GFP parts. That means 3 biobricks: scaffold, 2 split GFP. Yesterday got purified RNA of the scaffold (but didn’t denature, so a little uncertain). Will move onto doing gel shift assays once the constructs are obtained. Aug. 14th, send first part, Aug 17th sent second part to courtney. She canceled order because thought the 2 were the same. Ordered the parts finally on the 24th. Suggested is 10-12 business days, but will probably obtain it in mid-september. Can’t biobrick the 2 split GFP parts until the synthesized constructs are received. Uros will biobrick the scaffold on his own, but will need help when the split GFP parts come in.
 +
 +
Roles to fill:
 +
- fluorescence testing: Angela
 +
- biobricking everything: Isiah, with help from Adi
 +
- RNA/protein gels: Uros
 +
- cloning (not biobricks):
 +
 +
 +
 +
Advisors meeting
 +
present: Kori, Brad, Todd, Ahmet
 +
 +
Upcoming deadlines: abstracts, safety questions, track selection due September 7th
 +
- ongoing deadlines: poster, presentation, wiki (WIKI FREEZE is Oct. 3)
 +
- regional jamboree: Oct. 12- 14
 +
 +
Currently have: control YFP, wt puf binding site YFP, WT PUF.
 +
- co-transformed control YFP + WT PUF, and then wt puf binding site YFP + WT PUF in DH5a
 +
- results of fluorescence testing: control YFP does not glow but it should, binding site YFP does not glow either, but need to clarify the behavior of the control. (blast test reveals there should be no other PUF binding site in the YFP, so maybe the control binding site is actually not working. there could also be interference activity between the YFP and PUF).
 +
- have we perhaps mixed up what we think is control and puf binding site YFP?
 +
*** will try the PUF with mcherry instead, to see if it’s just an issue with the YFP. Also, use new cuvettes for the transformations. 
 +
 +
Will try in the future:
 +
- subclone YFP into pBAD (was previously in protet) 
 +
- back up plan from UNC’s Dr. Wong: mutant PUF binding to Lac Z in BL21
 +
 +
RNA Scaffold update:
 +
- tried to use primer extension for a week to tether split GPF and PUF, but it failed so ordered the parts for synthesis. The parts were ordered on the 24th of August. The quote was that they would come in 10-12 business days, but it’s pragmatic to expect it will take longer.
 +
- Transformed RNA scaffold, prepped, and got results for in vitro transcription. Got low concentrations and a weird value from the plate reader. Did another run of in vitro transcription with better results. optimistic about new results and got pure RNA scaffold (but didn’t denature ladder and didn’t use a certain buffer for the ladder). Therefore the ladder is incorrect. However, feels confident in result because obtained a single, defined band of notable concentration. Ready to do gel shift assays when the split GFP parts that were ordered finally arrived.
 +
- Needs funding to be able to continue this research in the Hergenrother lab. Need acrylamide casting equipment, RNAse zap. For the future would also need to buy the nickel and tine reagents.
 +
- don’t buy the gel box, just need the reagents. look for a gel box somewhere around the IGB. Could also just buy pre-made gels.
 +
- concentration of RNA? paper suggests 1000 fold, has used 100 fold. apparently that alone is enough to see a shift. However, that can be optimized.
 +
- the potential to do flow cytometry. There are locations for this on campus, but they might not be bacteria friendly and an hourly fee is also required to use the equipment.
 +
- in the next week will try to purify mutant and WT PUF, and then do gel shift assays with them.
 +
- need a distribution of work for all of this.
 +
 +
Writing the abstract (due Sept. 7)
 +
- a paragraph, similar to what would be in a paper
 +
- can write about things we haven’t performed yet, but need to be realistic
