Protocol Available protocols: Western Blotting Specificity / Sensitivity His-Tag (27E8) Mouse Monoclonal Antibody (HRP Conjugate) detects recombinant proteins containing the 6xHis epitope tag. This antibody conjugate recognizes the 6xHis-tag fused to either the amino or carboxy terminus of targeted proteins in transfected cells. Species Reactivity: All Species Expected Source / Purification Monoclonal antibody is produced by immunizing animals with a 6xHis synthetic peptide. Background Epitope tags are useful for the labeling and detection of proteins using immunoblotting, immunoprecipitation, and immunostaining techniques. Because of their small size, they are unlikely to affect the tagged protein's biochemical properties. A variety of plasmids contain DNA that encodes an amino-terminal tag consisting of six histidine (6xHis) residues followed by an extended multiple cloning site. The 6xHis tag on the expressed recombinant proteins allows for efficient coupling to Ni affinity resins and purification by single step chromatography (1). As is the case with other protein tag systems (2), this polyhistidine tag can often be cleaved at sites recognized by proteases such as thrombin and enterokinases to isolate the protein of interest (1).
