Aplicación

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.

Acciones bioquímicas o fisiológicas

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.

Calidad

At least 80% dephosphorylated.

Nota de preparación

Enzymatically prepared from C6780.

Insulin autoantibodies (IAAs) often appear as the first sign of islet cell autoimmunity in prediabetic children. Because cow's milk contains bovine insulin, we followed the development of insulin-binding antibodies in children fed with cow's milk formula. Bovine insulin- and human

Dietary factors are suspected to play an aetiological role in the development of insulin-dependent diabetes mellitus (IDDM). We analysed cow's milk formula, betalactoglobulin, and bovine serum albumin antibodies by an enzyme-linked immunoassay in unselected children with newly diagnosed IDDM and

We report a nanofluidic device for the label-free detection of phosphoprotein (PPn) analytes. To achieve this goal, a metal ion chelator, namely 4-[bis(2-pyridylmethyl)aminomethyl]aniline (DPA-NH2 ) compound was synthesized. Single asymmetric nanofluidic channels were fabricated in polyethylene terephthalate (PET) membranes. The

We present here a first appraisal of the phosphorylation site specificity of KIS (for 'kinase interacting with stathmin'), a novel mammalian kinase that has the unique feature among kinases to possess an RNP type RNA-recognition motif (RRM). In vitro kinase
