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.
Preparation Note
Reductive methylation of C5890 by the method of Cabacungan, J.C., et al., Anal. Biochem., 124, 272 (1982).

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.
