Depositor Comments

The BAC vector is derived from the E.coli F plasmid. The BAC vector was cloned into the high copy vector pK18, to increase yields. The BAC vector is typically excised by PacI. The BAC vector contains genes for participation (sopA, B,C, a repE gene (required for replication) and an origin of replication (oriS). There is also a chloramphenicol resistance gene. The BAC vector carries a gpt gene, driven by the HSV tk promoter; the gpt gene is followed by the SV40 polyA signal sequence (ca 125 bp). The BAC vector is terminally flanked by loxP sites. The plasmid contains also a 1.5 kb EcoRI-fragment from the murine herpesvirus MHV68. The sequence of pK18 is available from Genbank ACCESSION M17626.
