Properties of ATPase of gastric mucosa V. Preparation of membranes and mitochondria by zonal centrifugation

Academic Article


  • Using zonal sucrose density gradient centrifugation methods to fractionate the subcellular components in gastric mucosal homogenates have been developed. Methods are described which give high yield or rapidity in fractionation. A procedure is described which enables large-scale preparations of smooth walled vesicular membranes containing HCO3--ATPase activity free from mitochondrial contamination as assessed by electron microscopic morphology and undetectable succinic dehydrogenase or monoamine oxidase activity. A method to purify gastric mitochondria is also described. © 1973.
