General description
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.
Application
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[1] and a subtilisin analog that had been produced by site-directed mutagenesis.[2]

Protease substrate that has been used to assay basilase[1] and a subtilisin analog that had been produced by site-directed mutagenesis.[2]
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
Biochem/physiol Actions
Casein is highly preferred as a drug delivery vehicle. It possess antioxidant activity.

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
