Merck, 444258-1MG, MMP-14 Substrate I, Fluorogenic

General description
A fluorescence resonance energy transfer (FRET) peptide substrate for the detection of MMP activity (kcat/km = 730,000 M⁻¹s⁻¹ for MMP-14 (MT1-MMP) and 36,000 M⁻¹s⁻¹ for MMP-11 (ST3); pH = 7.5 at 25°C). Excitation max.: ~328 nm; emission max.: ~400 nm.
A specific fluorescence resonance energy transfer (FRET) peptide substrate for the detection of MMP activity. (kcat/Km = 7.3 x 10⁵ M⁻¹s⁻¹ for MMP-14 (MT1-MMP) and 3.6 x 10⁴ M⁻¹s⁻¹ for MMP-11 at 25°C, pH 7.5).
