WebLocalization of nucleotidases dependent on Ca 2+ was investigated cytochemically in axenically cultivated trophozoites of Entamoeba histolytica, strain HM-1:IMSS, with an electron microscope. Ca 2+-dependent ATPase (EC 3.6.1.3) activity was found on the plasma membrane and on the inner surface of the limiting membrane of a few … WebCa2+ (Mg2+)-ATPase (ecto-ATPase) in rat hepatocytes was determined by several methods. 1) Two polyclonal antibodies specific for the ecto-ATPase were used to examine the distribution of the enzyme in frozen sec- tions of rat liver by immunofluorescence. Fluorescent staining was observed at the bile canalicular region of hepatocytes.
