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
(In lab: JV, AV, HB)
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)
Issue:
- After checking the the sequencing it was evident that our promotor is always off. It is turned off by the product of the gene TetR. Which is not part of our construct.

| 0 | 0.071 |
| 1 | 0.390 |

| 2.5 (T1) | 1.250 |
| 3.5(T2) | 3.04 |
| 4.5(T3) | 2.75 |
Results: Ran samples on a 15% SDS-page. The gel did not show any signs of over-expression.
Objective: To determine if maxipreps were successful via restriction by NotI and running on 1% Agarose gel
Method:
1) Restriction:
| Component | Volume (µL) |
| DNA | 0.071 |
| Buffer Orange | 0.390 |
