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).
