Description
Suc-Leu-Tyr-AMC is a fluorescent substrate for calpain I and II and papain (another cysteine protease), and used for measuring the chymotrypsin-like peptidase activity of the 20S proteasome (excitation max: 360 nm; emission max: 460 nm). Suc-Leu-Tyr-AMC can also be cleaved by the Ti protease from E. coli
