[Isolation and partial characterization of receptor sites of normal human lymphocytes for lectins]

Glycoproteins of the lymphocyte surface are involved in many membrane mediated events. Their specific carbohydrate determinants might interact with lectins. Purification of macromolecules released from normal human lymphocytes by trypsin was performed using gel filtration and affinity properties for Ricinus sanguineus agglutinin. Some structural and biochemical characteristics are given. Relation to HLA determinants and surface immunoglobulins is discussed.
