Abstract:
The authors have studied the whole carboxyl groups of the platelet membrane using liquid phase electrophoresis and an initial step of activation of the acid group by a water soluble carbodiimide (ethyl-l-diméthyl-aminopropyl-3-carbodiimide), followed by the action of a nucleophilic molecule. The calculation based on the theory of Gouy-Chapman have shown the existence of 24, 7.10(5) groups per cell. That is a number about 2.5 fold superior to the carboxyl groups of sialic acid as determined by the action of neuraminidase.
