Faige's Work:
May 26-June 2: Made agar plates with different antibiotics; learned techniques
June 3: Received primers for leader sequences
June 4: Purified genomic XL1-Blue DNA
June 5-10: Unsuccessful PCR of 3 primers; digestion, ligation, and transformation (DLT) of 3 ccdB plasmid DNA
June 11: Miniprepped ccdB
June 12-19: Continued toggling with annealing temperatures for all 8 primers, 2 were successful!
June 22-24: DLT of ccdB with two successful leader sequence PCR reactions; DLT of RBS; DLT of promoter
June 25: Three-way DLT of RBS and promoter into ccdB plasmid
June 29: Received 6 long primers (for the 6 unsuccessful ones) and ran PCR on them, 4 were successful!
June 30-July 9: Resumed tweaking conditions for two remaining unsuccessful primers; DLT of 4 recently successful leader sequence PCR reactions, and three-way DLT of each of first 2 successful leader sequences with RBS/promoter into ccdB; DLT of RFP DNA; received RFP primers
July 10-14: Three-way DLT of the 4 later successes with RBS and promoter; three-way DLT of cytoslac with 2 earlier leader sequence/RBS/promoter
July 15: Ran PCR on RFP primers; tweaked conditions for unsuccessful ligation reactions
July 16-21: Three-way DLT of RFP and 1 earlier leader sequence/RBS/promoter; DLT of RFP DNA [as a simple Biobrick(BB)]; continued tweaking of previously unsuccessful DLTs; gel extraction of cytoslac digests (to remove resistance)
July 22-23: Transformation of RFP BBs into BL21 DE3 cells; Three-way DLT of RFP with other 5 successful leader sequence/RBS/promoter combinations; DLT of pure cytoslac with 4 recently successful leader sequence/RBS/promoter combinations; transformed 2 successful cytoslac/leader sequence/RBS/promoter combos into BL21 DE3 cells
July 24: Made 2XYT-media liquid cultures of BL21 DE3 cells and stimulated with IPTG; Also added IPTG to a plates of BL21 DE3 cells. No expression.
