Applications
UsesFLAG peptide is a multifunctional fusion tag for the purification of recombinant proteins. FLAG peptide maintances the natural folding of its fusing proteins. FLAG peptide can be removed by enterokinase, and eluted under non-denaturing conditions[1].
Additional notes
DefinitionChEBI: 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.
