Glycosylated kappa-caseins and the sizes of bovine casein micelles. Analysis of the different forms of kappa-casein.

Fast protein liquid chromatography (FPLC) of the kappa-casein from bovine casein micelles of different sizes is used to demonstrate that the proportions of glycosylated and non-glycosylated forms of kappa-casein do not vary with micellar size. The results suggest that glycosylated kappa-casein is distributed similarly to unglycosylated kappa-casein within the micellar structure.
