Description

General description

An internally quenched peptide substrate that is optimized for calpain-1 amino acid recognition motifs at the primed as well as the non-primed sides. Shown to be kinetically superior, in terms of turnover rate, to Calpain Substrate III, Fluorogenic (Cat. No. 208771), Calpain-1 Substrate, Fluorogenic (Cat. No. 208748), and Calpain Substrate II, Fluorogenic (Cat. No. 208731) by ~8-, 18-, and 310-fold, respectively.
