Effect of Gly-Sar Concentrations and Membrane Potential on % Ethanol (200mM) Inhibition of Gly-Sar Uptake by hPepT1 (n = 3 to 7)

Membrane potential	Gly-Sar concentration
	0.2 mM	1 mM	5 mM	20 mM
−30 mV	68 ± 13	68 ± 5	66 ± 4	70 ± 4
−50 mV	66 ± 12	63 ± 4	58 ± 4	63 ± 4
−110 mV	74 ± 13	63 ± 4	60 ± 3	64 ± 2

Gly-Sar-induced currents were obtained at different concentrations of Gly-Sar and membrane potentials in the presence of 200 mM ethanol (n = 3 to 7).
