Description: The pGEM ® -T Vector Systems are convenient systems for the<br />

cloning of PCR products. The pGEM ® -T Vector is prepared by cutting the<br />

pGEM ® -5Zf(+) Vector with EcoRV and adding a 3´ terminal thymidine to<br />

both ends. These single 3´-T overhangs at the insertion site greatly improve<br />

the efficiency of ligation of a PCR product into the plasmid by preventing<br />

recircularization of the vector and providing a compatible overhang for<br />

ligation of PCR products generated by certain thermostable polymerases.<br />

These polymerases often add a single deoxyadenosine, in a template-<br />

independent fashion, to the 3´-ends of amplified fragments.<br />

The multiple cloning site is flanked by recognition sites for the restriction<br />

enzyme BstZI, allowing release of the insert by a single-enzyme digestion.<br />

Alternatively, a double digestion may be used to release the insert from the<br />

vector. The pGEM ® -T Vector System II contains JM109 Competent Cells in<br />

addition to all of the pGEM ® -T Vector System I components.<br />

Features:<br />

• Rapid Ligation: The 2X Rapid Ligation Buffer provided allows reactions<br />

to be completed in 1 hour at room temperature.<br />

• Blue/White Screening: T7 and SP6 RNA polymerase promoters<br />

flank a multiple cloning region within the α-peptide coding region<br />

for β-galactosidase. Insertional inactivation of the α-peptide allows<br />

recombinant clones to be directly identified by color screening on<br />

indicator plates.<br />

• f1 Origin of Replication: Allows the preparation of single-stranded DNA.<br />

Storage Conditions: Store competent cells at –70°C; store all other<br />

components at –20°C.<br />

For Research Use Only. Not for Use in Diagnostic Procedures.<br />

Description: The pGEM ® -T Easy Vector Systems are convenient systems for<br />

the cloning of PCR products. They offer all of the advantages of the pGEM ® -T<br />

Vector Systems with the added convenience of recognition sites for EcoRI and<br />

NotI flanking the insertion site. Thus several options for removal of the desired<br />

insert DNA with a single restriction digestion are provided. The pGEM ® -T<br />

Easy Vector System II contains JM109 Competent Cells in addition to all of<br />

the pGEM ® -T Easy Vector System I components.<br />

Features:<br />

• Flexible: The multiple cloning site is flanked by restriction enzyme sites for<br />

BstZI, NotI and EcoRI, allowing three options for removal of the insert with a<br />

single digest.<br />

• Rapid Ligation: The 2X Rapid Ligation Buffer provided allows reactions to<br />

be completed in 1 hour at room temperature.<br />

• Blue/White Screening: T7 and SP6 RNA polymerase promoters<br />

flank a multiple cloning region within the α-peptide coding region<br />

for β-galactosidase. Insertional inactivation of the α-peptide allows<br />

recombinant clones to be directly identified by color screening on<br />

Purification of PCR products enhances cloning success. A 500bp PCR<br />

product was purified with the Wizard ® SV Gel and PCR Clean-Up System<br />

and cloned into the pGEM ® -T Easy Vector. Both the percent recombinants<br />

and total number of colonies increase with a pure PCR product. White bars<br />

represent recombinant colonies. Blue bars represent nonrecombinant colonies.<br />
