Collagenase-3 Substrate, Fluorogenic Yellow lyophilized solid. Supplied as a trifluoroacetate salt. PROTECT FROM LIGHT. PROTECT FROM MOISTURE. A quenched fluorescence substrate for MMP-13 (collagenase-3; kcat/Km = 1.09 x 106 M-1s-1). Less efficient as a substrate for MMP-1 (fibroblast collagenase) or MMP-8 (neutrophil collagenase). Purity: ≥98% by HPLC. Excitation max.: ~325 nm, Emission max.: ~393 nm MCA-Pro-Cha-Gly-Nva-His-Ala-Dpa-NH2 [Cha = L-cyclohexylalanine; Dpa = 3-(2,4-dinitrophenyl)-L-2,3-diaminopropionyl; Nva = L-norvaline] Ref.: Knauper, V., et al. 1996.
