While we are making and testing promoter mutants, we started making repressor mutants.  We'll need them eventually and the mutagenic PCR's don't take too long to do while things are slow.  However, testing out these mutants and finding a good range of repression is the tough part.  We also cut the wild-type repressors for construction of our testing plasmid.

Set up PCR reactions in order to Gibson our project togetherThe parts PCR'd were c0012, C0051, C0040, I13458, I13453, E0240, R0010, R0051, and R0040Will see how they look on a gel and then Gibson them togetherSo many primers!

Today was a really fun day!  We did some minipreps in the morning but then drove down to UC Berkeley for a NorCal iGEM picnic.  We got to talk with our fellow iGEMers from UCSF and Berkeley and got updates on how their projects were going.  It was nice to see that there is a community of synthetic biologists in Northern California that we can share ideas and materials with.  After a relaxed lunch, we had a small meeting to discuss how to achieve the medal requirements.  We discussed helping each other to fulfill one of the gold medal requirements with the Berkeley team since some of our software tools might be useful for their project this year.  We then got to see their lab and received some pBAD+AraC since those parts from the registry seem to be faulty.  Overall a really good day!

We weren't able to get all the parts for Gibson-ing our construct together.  We're still waiting on the 3 repressor PCRs and the pBAD promoter part.  The other's have been extracted and have decent concentrations for a Gibson mix.

We also proceeded with the construction of our testing plasmid. We digested C0040, C0012, C0051 at XbaI and PstI so that we could ligate it into B0034, which we cut at SpeI and PstI. Additionally, we cut  all of our promoter-GFP parts at EcoRI and SpeI, so that we could ligate them with I13453, cut at EcoRI and XbaI. We ran them on a gel, purified them, and plan on ligating and transforming them tomorrow.

Strange! Our plates from yesterday are covered with lots of green colonies, even the parts that don't contain GFP! We're going to do some tests; perhaps our media is contaminated, or the water that was used for ligations. We will re-ligate these parts, and re-digest from the minipreps. We ran these re-digestions on gel in order to extract the segment we wanted, but noticed some odd things about the bands. In the lanes containing our vectors, there were three bands where we would expect to only see one. This indicated to us that there was likely some contamination before our digestion. We went ahead and transformed the re-ligated gel purifications from earlier this week.

Once again, our plates are contaminated with green colonies. After some deliberation, we believe that our old media was contaminated with GFP-containing bacteria, and that media was used to culture some of our parts prior to a miniprep. Those minipreps, then, have both plasmids. We're going to re-streak the parts from glycerol stocks, and make new minipreps.

We continued with construction today and, once again, extracted the cut Promoters+GFP and repressors from a gel. We ligated the promoters+GFP in from of I13453 and the repressors before B0034. Hopefully this is the last time we will have to ligate and transform these parts.
