Figure 7From: Release of Ca2+ and Mg2+ from yeast mitochondria is stimulated by increased ionic strengthIncreasing pH increases mitochondrial Mg2+ efflux. The medium contained 0.3 M KCl, 10 mM HEPES for pH > 6.7 or 10 mM MES for pH < 6.7, the pH indicated, and 0.1 mM decavanadate (Na+). Mitochondria were spun down 4 min. after suspension and analyzed for Mg2+.Back to article page
