"WebbHis-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.
