| Further information: | The plasmid was designed for site-specific mutagenesis where the mutated sequence can be physically linked with a selectable marker (chloramphenicol). The plasmid provides resistance to ampicillin, but is sensitive to chloramphenicol. More than one mutagenesis round is possible via switching from ampicillin resistance to chloramphenicol resistance. pMa58 contains the replication origin of the single-stranded DNA phage f1 (clockwise orientated), so that it can be rapidly switched between the plasmid and the phage mode (ssDNA) of replication. The latter requires infection with a helper phage, e.g. M13KO7. After mutagenesis, use mutS strains for primary transformation (e.g. sup(-) strain WK6mutS, sup(+) strain BMH71-18mutS); for segregation of possible mutants: sup(-) strains (e.g. WK6). Name mentioned in Stanssens et al. (1989) is pMa5-8. |
