Anti-A hæmagglutinins from a non-leguminous plant-hyptis suaveolens poit

Abstract

CERTAIN plants, chiefly their seeds, contain agglutinins for the erythrocytes of various species. Whereas most plant agglutinins make no individual distinctions among human erythrocytes, some act selectively on one or other of the following blood-group antigens1: A, A1, B, H and N. Except for separable anti-H and anti-B agglutinins from the seed capsule of certain species of Euonymus, of the family Celastraceae, all specific seed agglutinins have hitherto been obtained from Leguminosae1. © 1959 Nature Publishing Group.
