Abstract
Complex-type glycopeptides from Human Tamm-Horsfall glycoprotein were fractionated by affinity chromatography on leucoagglutinin-agarose. An oligosaccharide species was retained by the lectin-gel, suggesting that it contains an alpha-mannose residue of the trimannosyl core substituted at C-2 and C-6 positions with beta-N-acetylglucosamine, as in tetraantennary oligosaccharides. The carbohydrate composition supported this branching pattern. The agglutination of neuraminidase-treated human erythrocytes induced by leucoagglutinin was selectively inhibited by the tetraantennary glycopeptide fractionI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
