solubilization of these glycoproteins and passage over a ricinus communis agglutinin i ( rca i ) sepharose affinity column revealed that no labeled 15b glycoprotein material bound , whereas 50 percent of the cho membrane glycoproteins bound and could be eluted with the haptene lactose , demonstrating that 15b cells are virtually devoid of membrane oligosacharides capable of binding to the rca i lectin .
