Wheat germ, Triticum vulgaris, lectin

Two lectins, one isolated from the horseshoe crab, Limulus poly-phemus (Pardoe and Uhlenbruck, 1970 Marchalonis and Edelman, 1968), and the other from wheat germ, Triticum vulgaris (Greenaway and LeVine, 1973 Bhavanandan and Davidson, 1975 Matsumoto and Codington, unpublished results), may attach at the cell periphery to receptor sites that include terminal glycoprotein-bound sialic acid units. The horseshoe crab lectin, purified and characterized by Marchalonis and Edelman (1968), was found by Pardoe and Uhlenbruck (1970) to be specific for terminal sialic acid residues.
