The pGEM®-T Vector Systems are convenient systems to clone PCR products generated by certain thermostable polymerases. These polymerases often add a single deoxyadenosine, in a template-independent fashion, to the 3´-ends of the amplified fragments. The pGEM®-T Vector is ready to use in ligation reactions, prepared by cutting the pGEM®-5Zf(+) Vector with EcoRV and adding a 3´ terminal thymidine to both ends. These single 3´-T overhangs at the insertion site greatly improve the efficiency of ligation of a PCR product into the plasmid by preventing recircularization of the vector and providing a compatible overhang for ligation of PCR products with A overhangs.
pGEM®-T Vector Map and Sequence
The pGEM®-T Vector is derived from the pGEM®-5Zf(+) Vector (GenBank® Accession No. X65308). The pGEM®-T Vector was created by linearizing the pGEM®-5Zf(+) Vector with EcoRV at base 51 and adding a T to both 3´-ends. The position of the T is indicated by * in the pGEM®-T Vector Sequence (.txt).
