General description

Casein is a major protein present in milk and constitutes up to 80% of total milk protein. It is a calcium phosphate-binding phosphoprotein present in mammalian milk. Casein in bovine milk is made of four types of peptides as αS1, αS2, β, and κ.

Biochem/physiol Actions

Casein has several uses as in adhesives, coatings and packaging material in the paper and food industries.

Warning

Toxicity: Standard Handling (A)

Reconstitution

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.

The development of advanced materials from biorenewable protein biopolymers requires the generation of more exogenous bonds to maintain the microstructure and durability in the final products. Casein is the main protein of milk, representing about 80% of the total protein.
