On the basis of the results presented we assume that the glycosylation of HSV glyeoprotein gC may lead to, at least, two populations of the gtyeoprotein gC, one with terminal N-acetylgalactosamine residues of oligosaccharides 0-glycosidically tinked to the polypeptide and the other without affinity-for HPA. However, both populations of gC contain similar proportions of oligosaccharides of the high 0304-8608/83/0076/0025/$ 02.80 S. OLOFSSO~ et al. : mannose or complex types with N-glycosidic carbohydrate-peptide linkages as indicated by their affinity for Con A.
