Verification of KAH187-MV8 plasmid
When troubleshooting the transfection of K562 cells, we need to use a positive control with the same promoter and backbone as our PcTF plasmid to determine the cause of low transfection efficiency - ie, is the uptake of plasmid low, or are cells not transcribing PcTF-RFP when they're transfected?
To that end I'm making more of the KAH187-MV8 plasmid, which contains a CMV promoter with two copies of the AmCyan gene and a nuclear localization sequence. Ran a plasmid miniprep on two cultures selected from transformation of DH5α-Turbo competent E. coli.
Expected size fragments (from Benchling): 3941, 1243, 1135, 288, 234
I'm not sure what's going on with this digestion. Colony 2 appears to match up with the expected fragments, except there's an extra band below the 3941 fragment. Colony 1's bands appear to be all over the place.
