[Detection of antigenic determinants of membranes using an insoluble peanut lectin].

The binding of lectins on insoluble supports may be used to detect the interactions occurring between these molecules and the sites of some receptors of membranes. An example is given, using the "anti-T" lectin extracted from peanut, to show the presence of determinants with terminal free glactose on the surface of erythrocytes and lymphocytes.
