In vitro packaging of exogenous DNA by Salmonella phage P22
The Journal of General Virology
|November 1, 1979
Abstract:
We describe in vitro conditions for packaging of exogenous DNA of Salmonella phage P22 which has terminally redundant, circularly permuted DNA. The method is a modification of the Kaiser-Masuda procedure. The most important aspect is to prepare all components (proheads, enzymes and concatemeric DNA) in end- cells. The influence of several factors such as DNA- and Mg2+ concentration and kinetics has been investigated.
