A polyhistidine-tag is an amino acid motif in proteins that consists of at least six histidine (His) residues, often at the N- or C-terminus of the protein.The tag serves as a vector for the induced expression and production of that protein. His-tags are useful for protein purification due to the strong ionic affinity of histidines to various metals used in chromatography columns that allow for a tagged protein to be selected for in high purity.
