His Tag Antibody (RMH01) [HRP] Summary

• Additional Information: Recombinant Monoclonal Antibody
• Immunogen: This His Tag Antibody (RMH01) was developed against a mixture of a peptide with 6xHis-Tag at the N-terminus and another peptide with 6xHis Tag at the C-terminus. This antibody is a Rabbit-Human Chimeric antibody, made by fusion of the antigen binding region (variable domains of the heavy and light chains, VH and VL) of NBP2-61482, with the constant domain of Human IgG1. The antibody is recognized only by an anti-Human IgG secondary antibody.

Background

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).
