Discovery of an ovine alpha S2-casein variant.

Abstract excerpt

A novel ovine alpha S2-casein variant has been detected using discontinuous polyacrylamide gel electrophoresis at alkaline pH, two dimensional electrophoresis and immunoblotting. It is characterized by a greater negative net charge and a lower isoelectric point compared with the most common ovine alpha S2-casein variant. The phenotypic frequency in the Manchega breed is 5.5%.
