title: Abundance of the Ca2+-pumping ATPase in pig erythrocyte membranes.
abstract: The Ca2+-pumping ATPase (Ca2+-ATPase) was purified from human and pig erythrocyte membranes by calmodulin affinity chromatography in the presence of phosphatidylcholine. The amount of enzyme present in pig erythrocytes is at least 7 times greater than that isolated from human erythrocyte ghosts. However, the properties of the enzyme from the two species are similar in many respects.
