General description
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 chromogenic trypsin substrate.

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

Why do the bottoms of the vials/bottles of product B4875-100MG (Nα-Benzoyl-DL-arginine 4-nitroanilide hydrochloride) appear to have no bottom? How is the product contained within the vials despite this unusual appearance? Is this a packaging defect?
