      <td>- Over the weekend: checked inoculations and had no growth on the control eYFP, so reinoculated it. It proceded to fail again. <br />- Ran a 24 hour ligation of pBAD/ptet YFP constructs. Plated them, they failed again. <br />- Checked transformations of DH5a with ptet+control/PUF eYFP. Had a few small colonies! so inoculated. <br />- Did another ligation using Angela's new procedure. <br />- Also did inoculation of 10 tubes of DH5a for making competent cells.<br /></td>

      <td>- Ran a gel for PCR samples (control and PUF/YFP)<br />- Inoculations of YFP in protet grew, so made glycerol stock, miniprepped, and stored in the temp box in the -20. Also nandropped them. <br />- Did a colony PCR of the colonies with protet and control YFP or protet and PUF binding site YFP. Diluted the primers for this from 30 mM to 10 mM. <br />- Colony PCR fails. <br />- Digested PSB1C3 with EcoRI and PstI in buffer 2. Digested for 2 hours.<br /></td>

      <td>- Made 10 tubes of DH5a competent cells. <br />- Streaked out Control YFP and PUF binding site YFP from glycerol stock.<br />- Looked at the gel from the 7/2/12 digestions of PSB1C3. There were two bands again. Both PSB1C3 glycerol stocks have the same problem. The stocks could have been incorrectly prepared. Perhaps there was an insert in the stocks. <br />- Will likely just use linearized PSB1C3 from biobrick kit for ligation. <br />- Made 1L LB and autoclaved some more 1.5mL microfuge tubes.<br /></td>

      <td>- Double digestion of BBa_K157005/pETDuet-1 was ran again with EcoRI-HF and PstI-HF in NEB Buffer 4 with BSA for 4 hours. Digestion failed as neither the pETDuet-1 was present, nor was there presence of the split-CFP band. <br />- Digestion was ran again with creation of a supermix in order to assure correct pipetting under the same conditions except for 3 hours. Digestion failed once more, no presence of pETDuet-1 and extremely faint split-CFP band. <br />- pETDuet-1 and BBa_K157005 were both inoculated from glycerol stocks in order to miniprep more plasmid for further digestion. <br />- Digestion will be tried once more with vector concentrations of 500ng and 1000ng along with addition of Alkaline Phosphatase to see if there is any increase in yield. <br />- BBa_K157007 (split-cYFP) was transformed as well in order to be used if digestion of the BBa_K157005 part doesn't succeed.<br />- Streaked out plates all grew successfully. Performed colony PCR on them, but had an annealing time of 30 sec instead of 1 minute. <br />- Got primers for WT PUF in pBAD, diluted to 2.5*10^-5. <br />- Did PCR of the WT PUF for insertion into pBAD. Used hotstart mix, DMSO, and 2 minute annealing step. <br />- Ran colony PCR and WT PUF PCR on the same gel, got all primer dimers in every lane. Need to redo both.<br />- PCR'ed two more WT PUF samples. <br />- Started the following overnight cultures: 2 of the ISB 179 PSB1C3, 2 of the 6/4/12 prep PSB1C3, 1 of the Protet, 1 of the E0030 (YFP), two WT PUF. <br />- Transformed PSB1C3 from the biobrick kit 1 into DH5a, plated it as well.<br /></td>

      <td>- Inoculated BBa_K157005 and pETDuet-1 to make new volume stocks of plasmids. <br />- Concurrently plated BBa_K157005 and pETDuet-1 in case the inoculations from glycerol stocks don't work and so I can inoculate from colonies if needed. <br />- Plated BBa_K157007 (the split-cYFP part) in case it works better than the BBa_K157005 split-cCFP part. <br />- However, colonies did not grow even after plated two plates as a backup. <br />- Miniprepped BBa_K157005 and pETDuet-1 inoculations put in last night and got very low, unusable concentrations (perhaps due to inadequate incubation time). <br />- Miniprepped pETDuet-1 and BBa_K157005 from this morning and got higher concentrations. <br />- Double digested BBa_K157005/pETDuet-1 with EcoRI-HF/PstI-HF with BSA and Alkaline Phosphatase for 3 hours (BBa_K157005 was digested both at 500ng and 1000ng vector quantity). <br />- Gel purified both bands which seemed to appear better than previous attempts. Concentrations after purification were still fairly low so chances of successful ligation might be compromised.<br />- Redid PCR of WT PUF with a temp gradient of 59-63-67-71. Used the supermix. <br />- Redid colony PCR with a temp gradient of 59-63-67-71 and the colony PCR supermix. <br />- Inoculated BBa_157005. <br />- Ran a gel of the WT PUF for pBAD. Only the 2 lanes showed any bands at all - the ladder and the 59 degree lane (had the right band!) <br />- Redid another gel with more dye, but still saw nothing else. <br />- Ran a gel of the colony PCR and got all primer dimers. <br />- PCR cleanup on the successful 59 degree lane for WT PUF, yielded a nanodrop of 63.7 ng/uL. <br />- Digested the pBAD miniprep and the WT PUF from the PCR. <br />- Ran a gel of the digestion with high melt gel. Got bands of the right length, but WT PUF was very faint. <br />- Used procedure for gel extraction, yielded very low nanodrop! Did ligation anyways<br />- PCR'ed four samples of WT PUF for subcloning into pBAD. <br />- Ran a gel of the PCR products. Only the 59 and 71 degrees samples worked (63 and 67 didn't). <br />- PCR cleanup of the two samples that worked, and digested with HindIII and EcorI. <br />- Gel extracted the two bands, then ligated over night.<br /></td>

Need a recipe other than that in notes. <br />- Starting from scratch for YFP by redoing the PCR. Used DMSO and supermix.. Failed, getting ghost bands that are very faint and at the incorrect length.<br />- PCR'ed three more samples of WT PUF for subcloning into pBAD<br /></td>

Gel of digestion shows success. <br />- Performed gel purification, but got concentrations all under 6 ng/uL. <br />- Tried several ligations of control and PUf binding site YFP into protet anyways. Used 10:1 insert to vector ratios. Running ligations overnight.<br />- Did PCR cleanup on the three samples from yestereday, digested with EcorI and HindIII. <br />- Digested pBAD as well. <br />- Ran gel of the digests, only one of the PCR's worked, the digest of pBAD didn't work. <br />- Extracted the PCR sample digest that worked, and ligated it with a previously digested pBAD sample</td>
