Novel approach to the study of the antigenicities and receptor functions of carbohydrate chains of glycoproteins.

Abstract

This report describes the construction of neoglycolipids as a novel approach to determining the antigenicities and receptor functions of minute amounts of oligosaccharides derived from glycoproteins. Reduced oligosaccharides are converted into oligosaccharide alditols by controlled selective periodate oxidation and conjugated to phosphatidyl ethanolamine dipalmitoyl by reductive amination. The resulting neoglycolipids can be rendered multivalent by binding to polyvinylchloride or silica plates or they can be incorporated into liposomes and their antigenicities and receptor activities determined in low concentrations by direct binding or inhibition of binding assays. This approach, which has been successfully used with two monoclonal antibodies and a plant lectin, should be widely applicable to the direct analysis of O- and N-glycosidically linked carbohydrate chains of glycoproteins and proteoglycans both as antigens and recognition structures of diverse receptor systems.
