Analytical study of ionized or ionizable groups of platelet membrane

The knowledge of the molecular surface groups of the human blood platelets present a particular interest especially in some thrombotic processes or thrombocytopathies. The aim of this study was to approach quantitatively ionized or ionizable groups of the platelet membrane using liquid phase electrophoresis or physicochemical and analytical methods with specific reagents. A mean repartition of the principal groups (carboxyl, SH, amino and phosphate) on the membrane is obtained by cell electrophoresis.
