NFF-2 MCA-RPKPYANvaWMK(DNP)-NH2 A quenched fluorescence substrate for MMPs. MMP-3 (stromelysin-1) hydrolyzes this substrate (kcat/Km = 5.9 x 104 M-1sec-1) at a rate 60 times faster than the hydrolysis by MMP-1 (interstitial collagenase). NFF-2 shows little discrimination between MMP-3, MMP-2 (gelatinase-A; kcat/Km = 5 x 104 M-1s-1), and MMP-9 (gelatinase-B; kcat/Km = 5.5 x 104 M-1s-1). Supplied as a trifluoroacetate salt. 产品信息 Peptide Sequence MCA-Arg-Pro-Lys-Pro-Tyr-Ala-Nva-Trp-Met-Lys(DNP)-NH2 (DNP = 2,4-dinitrophenyl; Nva = L-norvaline) Form Lyophilized yellow solid Formulation Supplied as a trifluoroacetate salt.
