Suc-Ala-Ala-Pro-Phe-pNA is a colorimetric specific substrate for human pancreatic elastase and chymotrypsin (K_m = 60 µM). It also acts as a substrate for Cathepsin G, subtilisins, chymotrypsin , chymase, cyclophilin, and peptidyl prolyl isomerase.

Activity is quantified by the release of p-nitroaniline which is measured by absorbance at 405 nm.
