What is azocasein?

Answer 1

Azocasein is a chemically modified protein that was designed as a substrate for quantative assay of proteolytic enzyme activity.

Hope that helped!!

Answer 2

Azocasein is a synthetic substrate used in enzyme assays to measure protease activity. It is a derivative of casein, a protein found in milk, that has been modified with an azo dye to allow for easy detection of enzymatic activity. When proteases cleave azocasein, the azo dye is released, causing a color change that can be quantified spectrophotometrically.
