Figure 1From: The effect of EGTA and Ca++ in regulation of the brain Na/K-ATP-ase by noradrenalineDependence of inverse values of Na/K-ATPase activity (μmol Pi/hour × mg protein) on [Ca2+] concentration (mM), in the presence of 0.3 mM EGTA. Broken line shows inverse value of Na/K-ATPase activity (l/V0) in the absence of EGTA and Ca2+ ions.Back to article page
