July 5/2010 Evening

Objective: To over-express CFP complete in DH5α

Method:

1) Inoculated 6mL culture with ampicillin and glycerol stock A6-May 13,2010 CFP complete 2) Went in the shaker at 6:50pm

July 6/2010

Objective: To continue the over-expression of CFP complete in DH5α

Method:
1) Put both cultures (taken out of shaker at 9:15am) and put them in 500mL of LB w/ Amp.
2) initial OD was 0.071 (600λ)
