pCP20 is an ampicillin and CmR plasmid that shows temperature-sensitive replication and thermal induction of FLP synthesis. CmR and KmR mutants were transformed with pCP20, and ampicillin-resistant transformants were selected at 30°C, after which a few were colony-purified once nonselectively at 43°C and then tested for loss of all antibiotic resistances. The majority lost the FRT-flanked resistance gene and the FLP helper plasmid simultaneously. This vector was first published in 1995, by Dr. W. Wackernagel, Genetik, Fachbereich Biologic, University Oldenburg.
