| - | Scandal in the lab! It appears that someone at Caltech has edited our wiki, initially inserting the word 'chicken' into our project page. Then they broke our Java script - potentially accidentally. Easily rectified, but still irritating, especially since the project description deadline was yesterday. Have we been the victim of a not-so-droll ivy league-ish prank? Or is some oddly minded person co-opting this student's account? We've emailed their project supervisor, so hopefully it shouldn't happen again.

| |
| - | One night seems to have been too little time to accurately determine if the transformation worked, as we now have lots of e.coli colonies on the plates. The ''bacillus'' plates have not been so successful, but the plasmid was not optimized to ''bacillus'', potentially explaining their failure. We will need to make sure that we include more controls in future to work out where our experiments fail, if they should fail.
| |
| - |
| |
| - | In any case, we were able to induce the pBAD promoter with arabinose in the e.coli cells. Results can be seen in the lab book page.
| |
| - |
| |
| - | The construct we are hoping to submit to DNA 2.0 has also been partially designed. The fusion of the lux α subunit and the mOrange protein has been completed, as described in the project page '''(link in when a little more complete)'''. The v.haveyi operon that we are hoping to have codon optimized has also been tided up, with more appropriate spacings between the genes.
| |
| - |
| |
| - | Additionally, Andreas managed to finish his Arduino device. It now gives a response that is proportional to the ratio of the light intensities on the two light dependent resistors. By using a couple of coloured filters over the top of these resistors, we can measure the necessary spectral properties of our engineered luciferases. All the engineers need to do now is come up with a user interface.

| |
| - | Apologies from the editing parties at Caltech, apparently the remaining changes were not meant to be there. Unfortunately they also edited Brown's wiki. A storm may be brewing, depending how seriously they take the changes...
| |
| - |
| |
| - | Anyway, apart from that little drama, lots happened in the lab today. Jolyon recieved his magnesium ion riboswitch primers - see what we did with them in the lab book. Paul and Andreas also made a short film '''link''' about their instrumentation.
| |
| - |
| |
| - | Tom worked on making the construct we need to get ordered from DNA 2.0 using their program Gene Designer. He ran into a few issues, but Jim A. was able to give a few hints, and put him into contact with some friendly people in Newcastle who specialize in working with ''bacillus''. If they don't know the answers, no one will.
| |
| - |
| |
| - | We're also having some problems deciding what approach to take with the input side of things. Our system should be very flexible, so it would be good to use many different biobricks from the registry. However, very few have been characterized in ''bacillus''. Ideally we would want to find some way of transferring existing biobricks from e.coli so that they were reliable in ''bacillus'', but we may find getting the right sensory proteins into ''bacillus'' complex. The idea was floated that we might want to approach the problem as a business problem, and do some market research into what the hypothetical end consumers of our product might want to sense. This would mean pitching to a specific group, potentially obscuring the main point of the project (the breadth and flexibility of the lux based system and its quantitative measurement of concentrations). For example, if we decided to create an agricultural kit as our prototype kit, we would want to create nitrate sensors, iron sensors, osmolarity sensors, fluride sensors etc. However, this would mean leaving out some very interesting additional sensory components. See what we eventually went with on our human practices page '''link here when we've decided'''.

| |
| - | The day started with gel electrophoresis of the PCR fragments that were made yesterday. As can be seen in the lab book, our genomic extraction appears to have been successful. However, we haven't managed to make our vector properly. Another day of PCR and gel electrophoresis, I fear...
