General description

A specific substrate for pancreatic elastase (Km = 100 µM; Kcat/Km = 35,000 s-1 M-1 for rat pancreatic elastase; Km = 30 µM; Kcat/Km = 351,000 s-1 M-1 for porcine pancreatic elastase). Cleavage of substrate can be monitored at ~405 nm.



Suggested protocol: see Largman, C. (1983)
