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.
