Localization and immunochemical characterization of the lectin Evonymous europaeus receptor site on the glycoprotein from human O erythrocytes.

Purified and desialylated glycoprotein M from human O erythrocytes precipitates with B and H specific lectin from Evonymous europaeus seeds, both in PBS and 0.2% Triton X-100. Desialylated, N-terminal fragment (MT-1) obtained by trypsin digestion of M glycoprotein does not precipitate with Evonymous lectin but inhibits precipitation.
