Descripción

Descripción general

An 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 (K_m = 4.6 µM; k_cat = 11 s^-1). Cleavage occurs at the Tyr-Gly bond and results in enhanced fluorescence. Excitation max: ~490 nm; emission max: ~518 nm.
