Summary

The main components of bovine whole casein were characterized by electrofocusing; pi values of αs1-, β-, κ-, γ1-, γ2- and γ3-caseins were determined. A further identification of casein components was achieved by a 2-dimensional electrophoresis study. 2-Dimensional patterns of γ-caseins obtained from a hydrolysate of β-cascin by bovine plasmin are in good agreement with those of γ-caseins naturally present in whole casein.
