General description

Casein is a major milk phospho-protein and constitutes about 80% of the total protein content in milk. Bovine milk is composed of four types of casein such as, αS1, αS2, β, and κ. Casein exists as micelles in milk.

Application

Casein fluorescein isothiocyanate from bovine milk has been used:
  • as a substrate for semi-quantitative analysis of protease in Arabidopsis cells
  • to determine the caseinolytic activity of secreted LasB (elastase), alkaline protease and protease IV
  • for determining the SpeB (cysteine protease) proteolytic activity in Streptococcus pyogenes cells

highly sensitive protease substrate

Biochem/physiol Actions

Casein micelle system is involved in the prevention of pathological calcification of mammary glands.
