Thursday: Got sequences for my last part back (K112013), sequences were correct, so I am done with my basic parts. PCR for assembly vectors worked beautifully, retried ligating dud basic parts into assembly vectors and transforming.
Wednesday: Minimeeting, set up transformations for testing the assembly vectors. Set up PCR to make more assembly vectors, as first batch did not turn out very well.
Tuesday: Picked colonies for transformation yesterday.
Monday: Got sequencing data back, which was wrong yet again, so I restarted K112013 from PCR, and finished the transformation.

Sunday: Finished minipreps for Aron and Molly, also picked colonies for Madhvi. Reorganized E. coli plates, and restructured DNA stock database.
Saturday: Day off. Madhvi did miniprep for me.
Friday: Sequencing data came back, was scrambled, figured out that columns A and H, B and G, C and F, D and E got swapped, and was able to analyze results. Got a bad read again for K112013, so picked another colony and hoped it worked, otherwise I'll have to start over from PCR.
Thursday: Finished miniprep for two colonies from yesterday, sent DNA off for sequencing. Adobe Illustrator tutorial today.

Wednesday: Made more digested pBca1256 vector. Sequencing data has come in for K112000, K112001,K112002, K112004, K112013, and K112015. 4 of the 6 were perfect reads, but 2 were not, so I repicked colonies for those two parts, and will do a miniprep tomorrow.
Tuesday: Miniprep on the colonies I picked yesterday using the Qiagen miniprep kit.
Monday: Picked second colonies from the plates that had bad sequencing data, and grew them up in 3 ml of 2xYT media.

Sunday: I finished my DNA sequence analysis:
K112000~K112017 6.15.2008 Sequence Analysis
BX001:K112000 - Sequencing data totally off.
BX002:K112001 - One possible point mutation at bp 685, T that should be a G, but chromatogram data is low, so unsure. The mutation is significant, as it changes a Gly to a stop codon.
BX003:K112002 - Parent vector with mutations.
BX004:K112003 - Perfect match.
BX005:K112004 - One possible point mutation at bp 451, changing a Tyr to a Ser. Also, read data did not cover entire part.
BX006:K112005 - Perfect match.
BX007:K112006 - Perfect match.
BX008:K112007 - Perfect match.
BX009:K112008 - Perfect match.
BX010:K112009 - Perfect match.
BX011:K112010 - Perfect match.
BX012:K112011 - Perfect match.
BX013:K112012 - Perfect match.
BX014:K112013 - Low read quality.
BX015:K112014 - Perfect match.
BX016:K112015 - Point mutation at bp 103, changing a Ile to a Thr.
BX017:K112016 - Perfect match.
BX018:K112017 - Perfect match.
Saturday: I came in to do a miniprep of the bacteria I picked yesterday using the Agencourt miniprep kit. This kit uses magnetic beads that bind dna to purify dna. The dna was sent out for sequencing analysis.
Friday: I spent a few hours waiting for our colonies to grow big enouogh to pick. When the colonies were ready, we made 2xYT media, and grew the colonies in 1 ml of media in a 96 well plate.

We had our first mini-meeting today, where we talked about what we have done for the last two weeks(somewhat), and about various subjects related to synthetic biology(more so). The meeting was interesting and not painful.
After the meeting, I went down to the lab to take out our PCR product from the machine. I then purified the product using clonewell gels, digested, cleaned up the reaction with the zymo kit, and the started the ligation. I then had to leave, so Molly will finish the transformation for me. In return, I'll do her mini-preps on Saturday.

Our oligos arrived today(yay!). We started making our basic parts. I made a mistake while making the master mix - I didn't know the dNTPs were at 10 mM instead of 2 mM, so I added 5 times as much dNTPs than needed. This means our PCR reaction has a good chance of failing, since dNTPs bind Mg, which the DNA polymerase needs in order to copy DNA. The extra dNTPs will probably outcompete the polymerase. No DNA was seen after running the eGel, so we set up the PCR reaction again, this time adding the correct amount of dNTPs.
Yesterday I poured more plates; 1 liter of Amp/Kan, 1 liter of Amp/Cam, and 1 liter of Cam/Kan.

Today I poured plates. There were 3 liters of LB/agar media, to which I added Spe. The 3 liters made 150 plates.

In our demos this morning we transformed bacteria, plated them, picked colonies, grew them up, and extracted DNA. The afternoon was taken up by designing oligos for the basic parts will start making next week(hopefully).

Today we continued our part making demo. Yesterday we set up the PCR reaction, and today we cleaned up the PCR, set up the digestion, and also ran an analytical gel of the PCR product.
