through the use of the specific glycosidases neuraminidase and endoglycosidase f and affinity chromatography on lectin-agarose gels , we show here that the receptor is a glycoprotein that contains several complex n-linked carbohydrate chains consisting of terminal sialic acid and penultimate galactose in a beta 1,4 linkage to n-acetyl-d-glucosamine .
