Description

General description

An internally quenched, highly cathepsin K-selective, fluorogenic peptide substrate that is efficiently cleaved by CatK (k_cat/K_m = 0.426 µM^-1 S^-1), but not by Cathepsins B/L/S/F/H/V. Studies using WT and CatK^-/- mice reveal that the substrate is not cleaved by other proteolytic enzymes present in fibroblast lysates. Emission Max: 420 NM, Excitation Max: 320 nM.
