Figure 4From: A technique for quantifying intracellular free sodium ion using a microplate reader in combination with sodium-binding benzofuran isophthalate and probenecid in cultured neonatal rat cardiomyocytesThe long-term effects of aldosterone on [Na+] i in cardiomyocytes. Cardiomyocytes were treated with vehicle or aldosterone at a concentration of 0.1 nM to 100 nM for 24 h. The data are the means ± SE from 11 experiments. *P < 0.01 vs vehicle.Back to article page
