The pRSET vector is designed for high-level prokaryotic expression controlled by the strong bacteriophage T7 promoter. Expression is induced by the production of T7 RNA polymerase in BL21(DE3) E. coli. These cells also produce T7 lysozyme to reduce basal expression of target genes. The pRSET vector offers:

• Bacteriophage T7 promoter for high-level expression
• T7 gene 10 sequence to provide protein stability
• N-terminal polyhistidine (6xHis) tag for rapid purification with nickel-chelating resin and detection with an Anti-HisG Antibody
• N-terminal Xpress™ epitope for detection with the Anti-Xpress™ Antibody
• Enterokinase cleavage site for removal of fusion tag

A set of three vectors is provided (A, B, and C). Each has the N-terminal tag coding sequence in a different reading frame relative to the multiple cloning site to simplify in-frame cloning of your gene.
For Research Use Only. Not for use in diagnostic procedures.
