What is the difference between A1 and A2 protein types? All cows originally produced only the A2 protein, but a natural change occurred over a thousand years ago, which caused the A1 protein to appear as a genetic variation. Today, most milk comes from cows that produce both A1 and A2 ...
The IEF gel electrophoresis pattern of milk 尾-casein protein showed two distinct bands corresponding to A1 and A2 尾-casein protein variants at pI values 5.22 and 5.14 respectively and this polymorphism correlated positively with the results of PCR-RFLP with TaqI restriction enzyme. The present ...

Beta-casein is a major protein in cow’s milk, of which A1 and A2 are the most frequent variants. Recent evidence implicates A1 beta-casein consumption in mechanisms that are of potential importance to mental health, yet its possible effects on psycholog
