FLAG-Tag, or FLAG octapeptide, or FLAG epitope, is a polypeptide protein tag that can be added to a protein using recombinant DNA technology, having the sequence motif DYKDDDDK. It represents an early example of a nanotechnology device, in that it can be attached to a protein like a molecular handle, then used to manipulate the protein, and subsequently detached. It has been used for studying proteins in living cells and for protein purification by affinity chromatography.
Optimal dilution of the FLAG Tag antibody should be determined by the researcher.
Amino acids DYKDDDDK were used as the immunogen for the FLAG Tag antibody antibody.
After reconstitution, the FLAG Tag antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
