Description générale
Nα-Benzoyl-DL-arginine 4-nitroanilide hydrochloride (DL-BAPNA) is a chromogenic substrate for proteolytic enzymes such as trypsin, amidase, and balterobin. Hydrolysis of DL-BAPNA at the bond between the arginine and the p-nitroaniline moieties releases the chromophore p-nitroaniline, which can be detected by colorimetric analysis.

A trypsin fraction was isolated from the pyloric ceca of New Zealand farmed chinook salmon (Oncorhynchus tshawytscha) by ammonium sulfate fractionation, acetone precipitation and affinity chromatography. The chinook salmon enzyme hydrolyzed the trypsin-specific synthetic substrate benzoyl-DL-arginine-p-nitroanilide (DL-BAPNA), and was inhibited
