Today was a pretty easy day. We began with trying to continue the project that was very much unsuccessful yesterday. We wanted to make a composite part with the RFP insert downstream of the p-Tet promoter. We digested pBca9145-1144 to retrieve our RFP insert as well as pBca9145-9205, which contains the promoter. :( low and behold, we failed again. all the lanes with the RFP showed up beautifully, but no lanes showed up for the 9205 plasmid. BUT!! it may not be our fault because the 9205 DNA was never tested. who knows? so instead, we worked on our wikis (obviously) The day wasn't in total vain because I did read two articles on heme so I understand better now. yippee!

This day was super hectic. We all began by setting up PCRs with the new oligos we received. but there were only one set of pipetmans. since we're a team, we made do. I was overwhelmed by six PCR reaction tubes. One for hemB, one for hemD, and two each for hemA from R. and hemC since they both have internal restriction sites. After they completed, I ran the two PCRs for hemA and two PCRs for hemC on a gel to gel purify. Horrible result: only one PCR reaction from hemA and one PCR reaction from hemC worked. As a result, I extracted/dissolved the gels of the PCR reactions that worked and dissolved in ADB to store in the fridge. I can't proceed with two good PCR products without the other two. I then set up new reactions to redo my failed PCRs. One for the failed hemA and one for the failed hemC and ran these PCRs on the machines upstairs. Inbetween all of this, I ran an analytical gel to see my PCRs from hemB and hemD. Good news: they worked! I then took a picture of this gel and cleaned up the PCR product. Afterwards, I digested with Bg1II/XhoI/DpnI, ligated with the vector pBca9145-1144#5 that Austin has prepared and digested for us, and then transformed into DH110B competent cells. I made one plate for hemB and another for hemD. Quite a busy series of events!
