Localization

Depends on the target

Specificity

It recognizes both the free and protein-conjugated (either soluble or cell bound) form of hexa-histidine. This monoclonal antibody is highly specific to hexa-histidine and shows no cross-reaction with other structurally related compounds. It has a very high affinity for hexa-histidine and is excellent for use in various techniques. His-Tag Antibody detects recombinant proteins containing the 6xHis epitope tag. The antibody recognizes the 6xHis-tag fused to either the amino or carboxy terminus of targeted proteins in transfected cells. 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 Ni2+ affinity resins and purification by single step chromatography. As is the case with other protein tag systems, this polyhistidine tag can often be cleaved at sites recognized by proteases such as thrombin and enterokinases to isolate the protein of interest.

Background: His Tag

A his-tag (also known as histidine tag or polyhistidine tag) is a common epitope tag that typically consists of at least 6 histidine residues fused to either the carboxyl (C-) or amino (N-) terminus of a targeted recombinant protein to facilitate its purification and detection (1). The most common his-tag is the hexahistidine (His6/6-His) tag which has a theoretical molecular weight of 0.8kda (1). The histidine residues readily interact with transition metal ions such as Co2+, Ni2+, Cu2+, and Zn2+, making immobilized metal-affinity chromatography (IMAC) the preferred technique for his-tag purification (1, 2). Metal ions are immobilized and bound to by His-tags in the IMAC column via the histidine imidazole ring. The tagged protein can be eluted off the column by washing with buffers containing a low concentration of imidazole (1, 2). Due to its relatively small size, low immunogenicity, versatility under denaturing conditions, and minimal interference with the structure and function of proteins, the his-tag is one of the most widely used tags for protein purification (1-3).
