The lectin possessed agglutinating activities for human and rat sperm as well as human red blood cells. It was found to have Mr= 62,000 consisting of two dissimilar subunits of Mr= 18,000 and 13,000. It also cross-reacted with an antibody against the lectin of Osage Orange (Maclura pomifera). © 1985.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyArticleSCOPUS10.1016/0006-291X(85)90122-6
