General description

Chromogenic substrate for trypsin and other proteolytic enzymes.
Na-Benzoyl-L-arginine 4-nitroanilide hydrochloride (L-BAPNA) is a colorless, chromogenic substrate for proteolytic enzymes such as trypsin, actinidin, and papain.

Application

Nα-Benzoyl-L-arginine 4-nitroanilide hydrochloride has been used as substrate:
  • to measure papain activity in spectrophotometric amidase assay[1]
  • to measure the inhibitory function of human cystatin C (HCC) on the protease activity of papain by colorimetric assay[2]
  • for trypsin[3]
