General description

Azoalbumin is a substrate for assaying proteolytic enzymes, majorly trypsin, pepsin and cysteine proteinase. The assay method offers precision and is easy to perform.

Application

Azoalbumin has been used:
  • as a substrate for enzymatic assay of hyphal extracts
  • for screening general protease activity in spent growth medium extract
  • for screening S. rolfsii proteases

Preparation Note

Prepared from Bovine albumin, Fraction V (A 4503)

Substrates

A soluble chromogenic substrate for proteolytic enzymes.

Storage Class

11 - Combustible Solids
