General description

Casein is a calcium phosphate-binding phosphoprotein present in mammalian milk. It constitutes about 80% of the total bovine milk. Bovine milk is made of four types of casein such as, αs1-, αs2-, β-, and κ-caseins.

Application

Casein from bovine milk has been used as a component of normal medium for Drosophila culture , in the preparation of αS1-casein (CAS1_Bovin) , as a source of nitrogen (N) in experiment diets .

Packaging

500 g in poly bottle

Biochem/physiol Actions

Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.
Numerous experimental applications including use as a blocking agent in immunochemistry, recovery of enzyme activity from SDS extracted samples, and as a substrate for protease and kinase assays.
