Protection of foreign DNA against host-controlled restriction in bacterial cells. I. protection of F' plasmid DNA by preinfection with bacteriophages T3 or T7

D H Krüger et al. Mol Gen Genet. .

Abstract

Foreign F'lac plasmid DNA which is introduced into potentially restricting E. coli recipient cells can be protected from restriction by preinfecting the recipient cells with UV-inactivated T3 or T7 bacteriophages which express the ocr gene function. The recipient cells survive and are able to replicate themselves as well as the newly acquired plasmid.
