[Comparative research on erythrocyte anionic adenosine triphosphatase in vertebrates].

Studies have been made on the level of activity of anion ATPase and its sensitivity to anions in erythrocytic membranes from fishes, amphibians, reptiles, birds and mammals. Significant variations in these properties of the ATPase were found among the species investigated. Protein composition of erythrocytic membranes was also investigated by means of disc-electrophoresis in polyacrylamide gel in men, rabbit, rat, mouse, hamster, tortoise, crow and starling.
