PE-1831-20 |
| 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-1831-20 is A1 beta casein protein that is in its native form and purified from bovine A1/A1 commercial cow's milk collected from cows that are certified BSE and disease free by the manufacturer of the milk.
IMPORTANT: This product may give different OD readings as compared to the protein calibrator contained in our A1 Casein ELISA Kit due to its formulation. Thus it is NOT recommended for use as a standard or QC marker in the A1 ELISA assays. |
