Escherichia coli (E. coli) K-12, strain IM01B contains the hsdM (methylase) and hsdS (specificity) genes from Staphylococcus aureus MW2 clonal complex 1 (CC). This insertion mutant was produced in E. coli K-12, strain DC10B via recombination-mediated genetic engineering (recombineering).

E. coli K-12, strain DC10B is a universal host for constructing plasmids for introduction into staphylococci and was deposited as Δdcm. The lack of methylation allows plasmid DNA to bypass a conserved type IV restriction-modification (RM) barrier in staphylococci which has been identified as a major barrier to transformation with foreign DNA. E. coli K-12, strain IM01B was deposited as resistant to streptomycin.

Each vial contains approximately 0.5 mL of bacterial culture in Tryptic Soy broth containing 25 µg/mL streptomycin supplemented with 10% glycerol.
