Week of 2007/06/11

2007/06/13 Wednesday – Transformed the BioBricks into bacteria. Titered lambda phage into concentrations of 10, 100, and 1000 colonies per plate.
Used BioBricks:
E0040 GFP
J23100 and J23116 constitutive promoter
B0015 terminator
P0440 tetR gene
P1010 on 2K3 plasmid

2007/06/14 Thursday – Checked results of titered phage (concentration of initial phage sample seemed to be off). Picked one colony from the transformed bacteria and cultured overnight.

2007/06/15 Friday – Purified the plasmids from the transformed bacteria colony using a prep kit, added restriction enzymes and buffer solution. Plan to integrate the terminator, constitutive promoter, and the tetR gene system (RBS, tetR gene, and terminator) BioBrick parts onto the 2K3 plasmid.
[Part name; Enzymes used; Buffer]
P0440; Xba/Pst; Eco Buffer & BSA
B0015; Eco/Pst; Eco Buffer & BSA
P1010; Eco/Pst; Eco Buffer & BSA
constitutive promoter (J23100, J23116); Spe/Pst; NEB & Buffer 2

Week of 2007/06/18

2007/06/18 Monday - Gel electrophoresis of J23100, J23116, 2K3(P1010), P4040, and B0015
Cut DNA bands from gel, purified DNA using Qiagen kit
Prepared ligations for:
A. Insert B0015 into Vector 2K3 (two reactions, from two digest bands)
B. Insert P0440 into Vector J23100
C. Insert P0440 into Vector J23116

2007/06/19 - Appearance of colonies on ligation plates, no colonies on control plates. Set up PCR reactions for 6 colonies (cell suspensions) on each of the ligation plates (A1, A2, B, C).
Set up PCR for overlap extensions (lambda c1 60, GFP, etc) of DNA template + premade primers.
