Abstract excerpt
The stability in Escherichia coli of a mammalian expression vector (pCIneo) and its derivative candidate DNA vaccine (pGPV-PV) is described. These multicopy pMB1-type plasmids were found to recombine in several recA E. coli strains due to the presence of two 28 bp direct repeats flanking intervening sequences of 1.6 kb (pCIneo) and 3.2 kb (pGPV-PV). In this recombination event, one of the direct repeats and the...
