Studies on lectins. LIX. Isolation and properties of lectins from fruiting bodies of Xerocomus chrysenteron and Lactarius lignyotus

Abstract

The lectins of fruiting bodies of Xerocomus chrysenteron and Lactarius lignyotus were purified on Sepharose 4B containing immobilized fetuin. Both lectins agglutinate human erythrocytes nonspecifically at limit concentrations of 15 .mu.g/mL. Their erythroagglutinating activities are not inhibited by simple sugars; desialyzed fetuin, desialyzed glycoprotein from edible bird''s nest, and desialyzed mucin from porcine submaxillary glands are the most effective inhibitors.
