MMP Substrate III, Fluorogenic

A fluorescence energy transfer (FRET) peptide substrate with MMP cleavable Gly-Leu bond and EDANS/Dabcyl as fluorophore/quencher combination. Useful for the detection of MMP activity (k_cat/K_m = 619,000 M^-1s^-1 for MMP-2, 206,000 M^-1s^-1 for MMP-9, 40,000 M^-1s^-1 for MMP-3, 21,000 M^-1s^-1 for MMP-1; pH = 7.6 at 37°C). Exhibits a high degree of sensitivity, which is not affected by optical disturbances in biological media. Excitation max.: ~340 nm; emission max.: ~485 nm.

A specific fluorogenic resonance energy transfer (FRET) peptide substrate with an MMP cleavable Gly-Leu bond and EDANS/Dabcyl as fluorophore/quencher combination. Useful for the detection of MMP activity [k_cat/K_m = 619,000 M^-1s^-1 for MMP-2, 206,000 M^-1s^-1 for MMP-9, 40,000 M^-1s^-1 for MMP-3, and 21,000 M^-1s^-1 for MMP-1; at 37°C, pH 7.6 ]. Exhibits a high degree of sensitivity that is not affected by optical disturbances in biological media. Also useful for MMP activity measurements in synovial fluid and culture medium.
