A peripheral high molecular weight glycoprotein located at the surface of human platelets

Summary A high molecular weight glycoprotein solubilised during platelet membrane isolation appeared to be a peripheral component of the human platelet surface and was susceptible to the action of neuraminidase when added to washed platelet suspensions.Part of this work was performed at The Nuffield Institute of Comparative Medicine, Zoological Society of London, Regents Park, London (England).
