설명

일반 설명

Casein is a milk protein, that is not expensive and nontoxic. highly stable. This phosphoproteins accounts for 80% of the total protein present in bovine milk. Casein is a member of one of the larger family of secretory calcium?binding phosphoproteins.

애플리케이션

Casein, N,N-dimethylated from bovine milk has been used:

• in the determination of general proteolytic activity
• as a substrate to study the effect of dephosphorylation on the calcium-activated neutral proteases (CANP) proteolysis of paired helical filaments (PHF) II-τ
• in transglutaminase (TG) assay

Casein, N,N-dimethylated from bovine milk can be used in assays to detect and help determine the functional role of tissue transglutaminase (tTG) in disease. In particular, Casein, N,N-dimethylated has been used in the mechanic and kinetic analysis of tTG on protein substrates, which may be linked to neurodegenerative disease.

This preparation has less than 10% reactivity with 2,4,6-trinitrobenzenesulfonic acid (TNBS) compared to non-methylated casein.

Protease substrate that has been used to assay basilase and a subtilisin analog that had been produced by site-directed mutagenesis.

생화학적/생리학적 작용

Casein is highly preferred as a drug delivery vehicle. It possess antioxidant activity.
