Bovine A2 Beta Casein, Native Protein
Catalogue No.PE-1832-20DescriptionBovine milk may contain two types of beta-casein protein, A2 or A1, which differ by a single-point mutation at amino acid position 82 (P82/H82). Recent studies have shown that milk containing the A1 beta casein protein can contribute to issues including gastrointestinal discomfort after ingestion. There is some evidence of a link between ingestion of A1 beta casein protein and the development of Type 1 diabetes.PE-1832-20 is A2 beta casein protein that is purified in its native form from bovine A2/A2 milk to >95% purity. The milk is collected from commercial cows certified free of disease and BSE by the manufacture of the milk.Related productsBEK-2365-1P, Bovine A2 Beta Casein ELISA Kit (1 plate)C-1780-100, Chicken antibody to bovine A2 Beta Casein Protein: Affinity purifiedBatch No.Refer to the product label.Unit size20 ugSequenceBovine A2 beta casein differs from A1 beta casein at amino acid position 82 (P82)Other NamesBeta CaseinAccessionP02666 (CASB_BOVIN)Produced inAffinity-purified from organic, natural bovine A2/A2 milk.Molecular Weight~33 kDa (SDS-PAGE)Purity>95% (SDS-PAGE)Biol. activityNot testedApplicationsPurified A2 beta Casein protein can be used as a standard in ELISA or Western Blot applications.
