Invitrogen™ pTrcHis2 TOPO™ TA Expression Kit
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,
pTrcHis-TOPO® Features
- 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® Features
- 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
