V05_23_1 Preparing BioBrick plasmids with constitutive promoters

Experiment:
J23100 – 18C – x2547
J23114 – 20 I – x256
J23112 – 20 E – x1
resuspended in 10 µl water and stored at -20°C

V05_23_2 Chemical transformation of P1 18C and P1 20I in E. coli (DH10B)

Experiment:
For the chemical transformations the standard protocol was followed.
Observations & Results:
On all plates bacterial growth could be observed, even on the negative control plate. We suggest that the plates are all right, but the competent cells are not. The over night culture seems to have been prepared with cells already containing puc18 and thus an ampicillin resistance. The experiment has to be repeated we new competent cells.
