Our pTrcHis A, B, & C vectors are designed to offer enhanced translation initiation and high-level expression in E. coli. These vectors feature:

• High-level regulated transcription from the trc promoter
• Enhanced translation efficiency of eukaryotic genes in E . coli
• The lacO operator and lacIq repressor gene for transcriptional regulation in any E. coli strain< br>
This particular vector offers:

• C-terminal polyhistidine (6xHis) tag for rapid purification with nickel-chelating resin and detection with an anti-His(C-term) antibody
• C-terminal c-myc epitope for easy detection of fusion proteins with an anti-myc antibody

For N-terminal polyhistidine tag and Xpress™ epitope, please see our pTrcHis A, B, & C Vector.
