Low copy BioBrick temperature sensitive standard vector

pSB8S15(FRT) is a BioBrick standard vector with low copy pSC101ts replication origin (~5 copies per cell) and spectinomycin antibiotic resistance marker, especially usable for Lambda Red recombineering in E coli. The pSC101ts is a temperature sensitive pSC101 repelication origin and propagates at 30’C but stop replicating at 42’C. 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. The pSB8X15 series are especially suitable for carrying the FLP recombinase, since they can be removed by incubation at 42°C.
