WebThe his-tag has a high affinity for these metal ions and binds strongly to the IMAC column. Most other proteins in the lysate will not bind to the resin, or bind only weakly. The use of a his-tag and IMAC can often provide … WebHis-tag is a series of six to nine histidine residues fused to either the carboxyl or amino terminus of a recombinant protein. The small size of the His-tag, compared with other common epitope tags, makes it less likely to obstruct the target protein’s structure or function and more suitable to use under denaturing conditions.

WebDespite its broad application in protein purification, only little is known about the binding properties of the His-tag, and therefore almost no thermodynamic and kinetic data are available. In this study, we investigated the binding mechanism of His-tags to Ni(2+)-NTA. WebHistidine residues in the His tag bind to the vacant positions in the coordination sphere of the immobilized nickel ions with high specificity and affinity. Once proteins are bound, the beads can be precipitated using a magnet, washed, and proteins eluted in small volumes of buffer under native or denaturing conditions.
