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.

The transformation was successful. Numerous colonies on all plates as well as on the positive control. Now growth could be observed on the negative control plate, so the competent cells are preparation of the competent cells was correct this time. Additionally, no growth could be observed at the 14N plate. This is the only vector containing a kanamycin resistance instead of ampicillin. Eventually, the kanamycin concentration was too strong and inhibited growth.<br>

The strain (DH10B) grows very fast, thus try not to incubate too long to prevent formation of satellite colonies. <br>

The cells hosting plasmids with strong promoters are colored red due to the rfp gene fused to the promoter. This phenomenon can be used to verify correct transformation.
