Abstract

Purification and characterization of a glycopeptide from buffalo colostrum is described. The sialoglycopeptide was fractionated and purified on Sephadex G-25 and QAE-Sephadex A-25. Its homogeneity was confirmed by RP-HPLC and electrophoresis. It consisted of NeuNAc, Fuc, Gal, Man, GlcNAc in the ratio 1:1:2:1:1 and Asp, Glu, Ser, Thr, Pro as major amino acids. Lys was found to be the N-terminal amino acid residue. Antibodies raised to the glycopeptide were immunogenic and were similar to blood group-A substance as determined by immunodouble diffusion and haemagglutination techniques.
