Cow’s milk contains six main proteins that affect its nutritional value: Alpha-casein S1 and S2, beta-casein, kappa-casein, alpha-lactalbumin and beta-lactoglobulin. Various mutations to the genes responsible for forming these proteins can alter its nutritional properties, cheese-making potential, digestibility by human consumers, etc.

This combined test analyses a cow’s kappa-casein for the A, B and E variants of the protein.
