Description_x000D_ Application_x000D_ α-Casein from bovine milk is an Immunoglobulin E (IgE)-binding epitope belonging to the Casein phosphoprotein family. It has been used in studies of children with insulin-dependent diabetes mellitus (IDDM), due to the strong cross-reactivity of α-casein antibodies with insulin. Studies of children displaying (IDDM) show higher levels of α-casein antibodies than control siblings, which may serve as a risk marker for IDDM._x000D_ Packaging_x000D_ 1 g in poly bottle_x000D_ 100, 250 mg in poly bottle_x000D_ Biochem/physiol Actions_x000D_ Clusters of phosphoserine in casein chelate iron and reduce its bioavailability. Partial enzymatic digestion of casein unmasks phosphorylated residues to alkaline phosphatase, permitting dephosphorylation and increasing the bioavailability of iron._x000D_ Quality_x000D_ At least 80% dephosphorylated._x000D_ Preparation Note_x000D_ Enzymatically prepared from C6780.
