Recombinant Protein: E. coli-Based Expression

A polyhistidine-tag is an amino acid motif in proteins that typically consists of at least six histidine (His) residues, often at the N- or C-terminus of the protein. It is also known as hexa histidine-tag, 6xHis-tag, His6 tag, by the US trademarked name HIS TAG (US Trademark serial number 74242707), and most … See more In general, proteins possess more or less the ability to coordinate metal ions on their surface, and it is possible to separate proteins by chromatography making use of the difference in their affinity.

They can be added to either end of the target protein, so they are either C-terminus or N-terminus specific or are both C-terminus and N-terminus specific. Some tags are also inserted at sites within the protein of interest; they are known as internal tags.
