Today we tested out error-prone PCR on the LacI promoter. We are adding MnCl2 to a few of the tubes and changing the nucleotide concentrations in other tubes. We want to test out some different screening techniques for a rapid hunt. Characterizing thousands, possibly tens of thousands of promoter mutants is quite a daunting task and we want to make it as easy as possible. We are looking to using a fluorescent cell sorter on campus which could narrow down a few good candidates for more rigorous testing. | Today we tested out error-prone PCR on the LacI promoter.

Today we ordered primers for mutagenesis of LacI promoter, cI promoter and tet promoter. They didn't have adequate overhangs on the forward primer which could make it difficult or possibly impossible to digest in order to put in a screening plasmid. We also ordered primers to replace RBS (Bba_B0032) in Bba_E0240 to Bba_B0034. | Today we ordered primers for mutagenesis of LacI promoter, cI promoter and tet promoter.

Week 1
Monday
Today we had our first real day of lab work. We settled ourselves into the lab bench that we will work at for the summer and set up our area. Along with familiarizing the new members with lab protocols, we had a productive day of hydrating and transforming. We really liked the linearized vectors that the Registry sent along with the plates, very nice addition. Today we designed what our wiki will look like and talked about some finer of the details of our project such as the exact construction method and a work plan. We are considering using Gibson assembly for all of our construction although in our lab it is still being debugged in a different side project. Results are promising though as biobricking has its drawbacks. Among other things, planning of an all-you-can eat sushi lunch is in the works. We will plan our work schedule around that.

Today we tested out error-prone PCR on the LacI promoter. We are adding MnCl2 to a few of the tubes and changing the nucleotide concentrations in other tubes. We want to test out some different screening techniques for a rapid hunt. Characterizing thousands, possibly tens of thousands of promoter mutants is quite a daunting task and we want to make it as easy as possible. We are looking to using a fluorescent cell sorter on campus which could narrow down a few good candidates for more rigorous testing.
We began work on the actual wiki with some code that I (Tim) wrote over the weekend. It works perfectly in an unrestricted webpage but once I put it in iGEM's wiki, it doesn't work. We'll have to figure this out. We cultured all parts and digested to check on a gel. All parts checked out. Sent out all hydrated parts to get sequenced.
We ligated mutants into screening plasmid to see if our error-prone PCRs had visible mutants.
Wednesday
Today we ordered primers for mutagenesis of LacI promoter, cI promoter and tet promoter. They didn't have adequate overhangs on the forward primer which could make it difficult or possibly impossible to digest in order to put in a screening plasmid. We also ordered primers to replace RBS (Bba_B0032) in Bba_E0240 to Bba_B0034.
