Comparison of binding proteins on the surface of murine tumor cells for two lectins active in the lectin-dependent macrophage-mediated cytotoxic reaction.
The binding proteins for Sarcophaga lectin and wheat germ agglutinin on the surface of Ehrlich ascites tumor cells were compared. Studies with antibody against the binding protein for Sarcophaga lectin showed that these two binding proteins are different. Since these two lectins are both active in the lectin-dependent macrophage-mediated cytotoxic reaction with Ehrlich ascites tumor cells as target cells, there must be multiple proteins on the surface of target cells that can trigger cytolytic reaction in response to different lectins in the presence of macrophages.
