Description
OverviewAn internally quenched fluorogenic substrate peptide derived from the calpain-1 cleavage site of α-spectrin. It is not recognized by trypsin or α-chymotrypsin and serves as a sensitive and specific substrate for calpain-1 (Km = 4.6 µM; kcat = 11 s-1). Cleavage occurs between Tyr-Gly residues and results in enhanced fluorescence.
