| Background | The DYKDDDDK peptide (Flag-tag) is a polypeptide protein tag that can be added to a protein using recombinant DNA technology. It can be used for affinity chromatography, and then used to separate recombinant, over expressed protein from wild-type protein expressed by the host organism. It can also be used in the isolation of protein complexes with multiple subunits. |
| Alternative | DDDDK tag; DYKDDDDK tag; Flag tag; DYKDDDDK epitope; DDK epitope |
