Today, I went through PCR purifications of 100 µL of each of the CpxP Promoter PCR Products using a Qiagen kit with the same modified procedure as yesterday. This second purification was done to gain more purified product. Most of the first purification was used up in doing a restriction digest and attempting to construct the CpxP promoter into Ampicillin-kanamycin and ampicillin-chloramphenicol plasmids. I also did this construction today, cutting with the restriction enzymes XbaI and PstI.

Dev Today I performed a plasmid switch of the CpxR promoter from an ampicillin resistant plasmid to an ampicillin-kanamycin resistant plasmid. Transformed the AK CpxR into competent cells.
