Structural formula: {0} (CAS {1})

FLAG peptide is an eight amino acid peptide consisting of L-aspartic acid, L-tyrosine, L-lysine, four L-aspartic acid residues, and L-lysine joined in sequence by peptide linkages. It is widely used as a fusion tag for the purification and detection of a wide variety of recombinant proteins.
