Low copy BioBrick standard vector

pSB4K15(FRT) is a BioBrick standard vector with low copy pSC101 replication origin (~5 copies per cell) and kanamycin antibiotic resistance marker, especially usable for Lambda Red recombineering in E coli. The backbone sequence is based on pSB3T5, but the E coli His operon terminator BBa_B0053 has been replaced with the late terminator of the Salmonella phage P22.

The resistance cassette is flanked by FRT sites (BBa_J61020) which allows for subsequent removal of the resistance cassette from the chromosome by the FLP recombinase.
