Bovine A2 Beta Casein, Native Protein

$277.00USD


Catalogue No. PE-1832-20
Description Bovine 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.
