| The pTrcHis- and pTrcHis2-TOPO® TA Expression Kits each contain two boxes. The TOPO® TA box contains 200 ng of linearized, topoisomerase I-activated pTrcHis-TOPO® or pTrcHis2-TOPO® vector, sterile water, dNTPs, 10X PCR buffer, a control template and primers, primers for sequencing or PCR screening, and an expression control plasmid. The One Shot® TOP10 box contains twenty-one, 50-µl aliquots of chemically competent TOP10 E. coli, S.O.C. medium, and a supercoiled control plasmid. Store the TOPO TA Cloning® box at -20°C. Store the One Shot® box at -80°C. All reagents are guaranteed stable for 6 months when properly stored. |

描述 |
The pTrcHis- and pTrcHis2-TOPO® TA Expression Kits allow fast, efficient cloning of PCR products into a prokaryotic expression vector for high-level, regulated expression from the trc promoter. The vector in each kit, pTrcHis-TOPO® or pTrcHis2-TOPO®, includes a minicistron element for enhanced translation efficiency of eukaryotic proteins in E. coli. Both vectors are provided linearized and activated with topoisomerase I for 5-minute TOPO® Cloning with >85% cloning efficiency. To simplify protein purification and detection, the pTrcHis-TOPO® and pTrcHis2-TOPO® vectors include the following features:
pTrcHis-TOPO®
• N-terminal Xpress™ epitope for detection with an Anti-Xpress™ Antibody
• N-terminal polyhistidine (6xHis) tag for purification using nickelchelating resin and detection with an Anti-HisG Antibody
• Enterokinase cleavage site for efficient removal of N-terminal fusion tags
pTrcHis2-TOPO®
• C-terminal c-myc epitope for detection with an Anti-myc Antibody
• C-terminal polyhistidine (6xHis) tag for purification using nickel-chelating resin and detection with an Anti-His(C-term) Antibody
