Lab Notebook

Date	Accomplishments
January 1-15	Met for the first time during class time as an Instructional Focus. Discussed project ideas and iGEM in general. Gave out protocols to study
January 16-31	Practiced transformations with p-GLO from Biorad. Learned about Bacterial Antibiotic resistance using Biorad Antibiotic Resistance Lab.
February 1-14	Discussed project ideas. Planned for visit to Georgia Institute of Technology, Styczynski Lab. Sold Pretzels for fund raiser.
February 15-28	Studied and took test over iGEM protocols and 3A Assembly. Finalized list of Biobrick parts of interest. Outlined initial ideas. Use K410000 to characterize cold shock heat generator.
March 1-14	Field trip to GA Tech on March 9 • Rehydrated J23119, J13002, J04450, K410000 • Miniprepped parts • Ran diagnostic gels • Sent parts for sequencing • Calculated concentration of DNA • Met with team members from GATech iGEM. Discussed the K410000 project. • New idea for project; isolate HybB and make it a Biobrick. GATech team will send their frozen stocks.
March 15-28	Worked on research for the new parts. Wrote Project proposal.
April 1-24	April 1st • Transformed again • Made Amp plates • Cataloged Gaucher 2010 box • Plated the HypB with RFP on Amp plates April 4th • Liquid culture results were analyzed • Took the HypB samples and mixed with Glycerol (Glyceroled Bio Bricks) and placed them in 80oC freezer • Streaked LB plates with HypB samples, promoter, and K410000 (bio brick) • Made more LB plates • Miniprepped hypB parts and K410 from Gaucher box • Calculated the DNA concentration • Calculated concentrations for sequencing • Wrote instructions for Cold Shock April 24th • Nanodropped with DNA concentrations • Ligation ( Protocol) • Digest of RFP, hypB, psBIC3, 410
May 1- May 14	• Transformation • RFP control and 410 RFP grew but only RFP has an expression • Ran transformation efficiency test with Protocol • Prep for experiment- plated 10 plates and inoculated 16 tubes • Experiment for temperature variation was successful but did not prove hypothesis
May 30th	Several of our members attended a safety training meeting, and are now certified in lab safety courses.
June 3rd	Designed primers and developed lab calendar
June 4th	Ordered primers
June 6th	We researched HybB and PSB1C3. Then chloramphenicol plates were made.
June 7th	We did a practice PCR reaction and ran a diagnostic gel to check practice our PCR. Primers came in, so we made stock solutions of a 1/10 dilution and a 1/20 dilution from the primers.
June 10th	We did a PCR of our HybB promoter and ran a gel. The gel showed that the temperature of our PCR was incorrect. Then we ran a gradient PCR with HybB promoter at deven temperatures ranging from 44.6°C to 53.3°C with the control at 54.5°C. Then we inoculated liquid stock with DH10 beta in order to purify genomic DNA.
June 11th	We ran a diagnostic gel, which showed the best temperature for PCR was 46.1°C and 53.3°C. On the gel we got 500 base pairs, which is the expected length of our primers and part. We used QIAprep for PCR cleanup.
June 12th	We met with Georgia Tech iGem team and heard their presentation and discussed cooperation and outreach. We did a double digest with EcoRl remix and PST1. We blasted all of our parts to check all of the DNA sequences against the parts registry. We also worked on the wiki and the poster.
June 13th	We repeated the double digest. We used Antarctic phosphatase to cut off the extra phosphates on the 5 prime ends of the backbone. We ligated the HybB promoter and the backbone and we included a control of just the backbone. Then we transformed the ligation mixtures of today and yesterday resulting in eight plates.
June 14th	We recorded the results from yesterday, then we did colony PCR on the colonies, choosing the ligation mixture that was a 2:1 ratio of HybB to backbone. We did a diagnostic gel with 16 colonies and analyzed our results. Unfortunately, our colony PCR failed. We do not know the reason for the failure, but we suspect that a)we did not put the colonies in the thermocycler for long enough, or b)the cells did not contain our part.
June 17th	We repeated the colony PCR.
