Glycosaminoglycans and acidic glycoproteins in rabbit uterus under estrogenic conditions.
Uterine slices obtained from the estrogen-treated rabbits were digested with pronase. Glycosaminoglycans and acidic glycopeptides were then isolated by Dowex 1 column chromatography and preparative electrophoresis on cellulose acetate membrane (Separax), in succession. Each subfraction thus obtained was identified by the mobility on Separax electrophoresis and the digestibility with mucopolysaccharidases (Streptomyces hyaluronidase, testicular hyaluronidase, chondroitinase AC, chondroitinase ABC and heparinase). The resulting data showed that each complex saccharide (hyaluronic acid, heparan sulfate, chondroitin sulfate A, chondroitin sulfate C, dermatan sulfate, sulfated glycopeptide and sialoglycopeptide) was separated into 2-5 fractions, indicating charge and/or molecular heterogeneity of each complex saccharide.
