from previous studies , it was established that the mb1 material from the surface of lymphocytes and endothelial cells comprises a set of acidic glycoproteins of mr ranging from 80,000 to 240,000 , and that cultured endothelial cells secrete a component with a molecular weight under reducing conditions close to that of the alpha 2-m subunit .
