title: Stability of the hybrid plasmid pIM138 and its curing by some eliminating agents.
abstract: Hybrid plasmid pIM138 was constructed by insertion of a chromosomal fragment with the threonine operon from Escherichia coli into the pBR322 vector. Molar mass of pIM138 was 2.8 Mg/mol. Heteroduplexes between pBR322 vector and pIM138 hybrid DNA molecules were prepared. The hybrid plasmid shows a high stability against the curing effect of rifampicin and clorobiocin in E. coli SK1590 thr host.
