Enhanced TA Cloning® kits—now with 15 minute, room temperature ligationsClose
The TA Cloning® Kit Dual Promoter with pCR™II vector provides a quick, one-step cloning strategy for directly inserting a Taq-amplified PCR product into a plasmid vector. The T7 and Sp6 promoters of the pCR™II vector allow in vitro transcription of the insert to produce sense or anti-sense products. The TA Cloning Kit Dual Promoter uses the pCR™II cloning vector and ExpressLink™ T4 DNA Ligase to generate a ligation product in a fifteen-minute, room-temperature ligation step. Reactions typically yield >80% recombinants containing inserts.
Features of the TA Cloning® Kit Dual Promoter: • Fast & convenient—15-minute, room-temperature ligation • Efficient—blue/white screening and >80% clones with correct insert • Flexible—choice of kanamycin or ampicillin resistance for flexible antibiotic selection • Hassle-free—eliminates any enzymatic modifications of the PCR product • Streamlined—does not require the use of PCR primers that contain restriction sites
The pCR™II vector provides: • 3'-T overhangs for direct ligation of Taq-amplified PCR products • T7 and Sp6 promoters for in vitro RNA transcription and sequencing • Versatile polylinker with flanking EcoR I sites for easy excision of inserts • M13 forward and reverse primer sites for sequencing
How TA Cloning® Works Taq polymerase has a non-template-dependent activity that adds a single deoxyadenosine (A) to the 3' ends of PCR products. The linearized vector supplied in this kit has single 3' deoxythymidine (T) residues. This allows PCR inserts to ligate efficiently with the vector.
Kit Configurations The TA Cloning® Kit is offered in a variety of configurations: with One Shot® INVF' Chemically Competent E. coli (K2050-01 and K2050-40), One Shot® TOP10F' Chemically Competent E. coli (K2060-01 and K2060-40), and without competent cells (K2750-20 and K2750-40) in 20- and 40-reaction kit sizes.
