Description

FLAG peptide: engineered as a tag for immunoaffinity purification of genetically-engineered proteins; amino acid sequence given in first source; a polar octapeptide [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

FLAG peptide : 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.

Drug Classes (1)

ClassDescription
peptideAmide derived from two or more amino carboxylic acid molecules (the same or different) by formation of a covalent bond from the carbonyl carbon of one to the nitrogen atom of another with formal loss of water. The term is usually applied to structures formed from alpha-amino acids, but it includes those derived from any amino carboxylic acid. X = OH, OR, NH2, NHR, etc.
