Intracellular and Extracellular Concentrations of Na(+) Modulate Mg(2+) Transport in Rat Ventricular Myocytes

Apparent free cytoplasmic concentrations of Mg(2+) ([Mg(2+)](i)) and Na(+) ([Na(+)](i)) were estimated in rat ventricular myocytes using fluorescent indicators, furaptra (mag-fura-2) for Mg(2+) and sodium-binding benzofuran isophthalate for Na(+), at 25°C in Ca(2+)-free conditions. Analysis included...
