NR-50349 is a preserved culture of Escherichia coli (E. coliDH5αλpir containing the E. coli-staphylococcal shuttle vector pKK30. Vector pKK30 contains the E. coli R6Kγ origin of replication and is for use in Staphylococcus spp. strains without LAC-p01. Vector pKK30 contains a single trimethoprim resistance cassette that is functional in both E. coli and Staphylococcus spp. pKK30 is identical to pKK22 except it lacks open reading frames required by USA300 strains needed for plasmid maintenance.  The complete pKK30 nucleotide sequence is available (GenBank: KX085043) and the vector map of pKK30 is available on the Product Information Sheet.

pKK30 was deposited in conjunction with pKK22 and E. coli strains DH5αλpir and GM2163λpir (available as a kit, BEI Resources NR-50352). pKK22 and pKK30 were created to maintain stability in E. coli and Staphylococcus species without antibiotic selection during in vitro and in vivo experiments. The E. coli R6Kγ origin of replication of both vectors requires pir+ for replication which is provided in either DH5αλpir or GM2163λpir E. coli strains.
