Abstract: | Platelet membrane glycoprotein Ib plays a major role in the binding of factor VIII/von Willebrand factor to allow platelet adhesion to subendothelium. We have used polyspecific and monoclonal antibodies to glycoprotein Ib and have demonstrated that both antibodies were directed to glycoprotein Is, a soluble fragment of glycoprotein Ib. By showing an inhibition of the binding of factor VIII/von Willebrand factor to control platelets in presence of the antibodies, it can be concluded that glycoprotein Is is involved in these binding sites. |
