Identification, isolation and some properties of lectin from the seeds of Indian coral tree [Erythrina variegata (Linn.) var. orientalis (Linn.) Merrill]

Abstract

A D-galactose-binding lectin agglutinating human erythrocytes has been purified from the seeds of the Indian coral tree (Erythrina variegata (Linn.) var. orientalis (Linn.) Merrill] by affinity chromatography on acid-treated Sepharose-6B gel. It has a higher reactivity for O-group erythrocytes. The lectin is a glycoprotein having a leucoagglutinating property.
