Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH2 (FS-6) is a quenched, fluorescent MMP peptide substrate designed for real-time quantification of MMP enzymatic activity. As an extended variant of the MMP substrate (FS-1), it demonstrates increased specificity against collagenases (MMP-1, MMP-8, MMP-13) and MT1-MMP, with higher specificity constants (Ex/Em=325 nm/400 nm).
