Design of fluorescence-quenched peptides. Peptides contain an N-terminal fluorescent donor, followed by six amino acid residues of the region flanking the dominant FAP endopeptidase cleavage site of human FGF21, ending with an additional C-terminal lysine conjugated to a dark quencher. Variants include substitution of the P1 proline with glycine, the P2 glycine with D-alanine or the entire homologous region of murine FGF21.
