Evidence for the occurrence of lactosaminoglycan in porcine kidney

Weakly acidic glycopeptides were obtained from he pronase digest of porcine kidney. The glycopeptides were digested with endo-beta-galactosidase. An oligosaccharide fraction was separated from the digest by gel-filtration through Sephadex G-50. The fraction contained galactose and glucosamine in an equimolar ratio.
