Description

The pGEM®-T Vector Systems are convenient systems to clone PCR products. The pGEM®-T Vector is 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 generated by thermostable polymerases that add a single deoxyadenosine, in a template-independent fashion, to the 3´-ends of amplified fragments.

The multiple cloning site is flanked by recognition sites for the restriction enzyme BstZI, allowing release of the insert by a single-enzyme digestion. Alternatively, a double digestion may be used to release the insert from the vector. The pGEM®-T Vector System II contains JM109 Competent Cells in addition to all of the pGEM®-T Vector System I components.

Features – Benefits

  • Rapid Ligation : The provided 2X Rapid Ligation Buffer allows reactions to be completed in 1 hour at room temperature.
  • Blue/White Screening : T7 and SP6 RNA polymerase promoters flank a multiple cloning region within the α-peptide coding region for β-galactosidase. Insertional inactivation of the α-peptide allows recombinant clones to be directly identified by color screening on indicator plates.
  • f1 Origin of Replication : Allows preparation of single-stranded DNA.
