EVIDENCE FOR TWO DIFFERENT Ca2+TRANSPORT SYSTEMS ASSOCIATED WITH PLASMA AND INTRACELLULAR HUMAN PLATELET MEMBRANES
The regulation of Ca2+ concentration in different cells involves two Ca2+ pumps. The presence of such mechanisms in human platelets is still controverted. We then investigated this question by using plasma and intracellular membranes obtained after simultaneous isolation by centrifugation ca 40% sucrose from a mixed 100,000 g membrane fraction.The Ca2+ uptake by the different membrane vesicles has been studied. Both membrane fractions took up Ca2+ and the Ca2+ transport systems exhibited a highdoi:10.1055/s-0038-1644490 fatcat:ze7ohom3avfxzaneqgsy7jn5la
