Please note that the pCaSpeR-bgal polylinker sequence presented in Gene Vol. 74, page 448 is incorrect. The correct sequence is:


This vector is described in Thummel et al. (1988) Gene 74: 445-456.
Restriction sites are marked : BamHI (B), HindIII (H), KpnI (K), PstI (P), EcoRI (RI), SalI (Sa), SmaI (Sm), SstI (Ss), XbaI (X). Note that only the PstI site can be used in the pCaSpeR-bgal polylinker, due to a downstream stop codon (underlined).
