Description: The polyclonal antibody reacts with the polyhistidine tag; the antibody was raised against a peptide containing the 6x histidine tag. The 6x histidine recombinant protein tag is made up of 6 histidine residues attached to either the amino or carboxy terminus of the protein being expressed. The recombinant protein can then be purified using immobilized metal ions, traditionally nickel, in a procedure termed immobilized-metal affinity chromatography. Further analysis of the protein can be achieved using an antibody specific to the 6x histidine in techniques such as western blotting and immunoprecipitation.
