Amplitude of overshoot current is enhanced by depletion of the Na+ gradient. Extracellular application of glycine stimulates an inward current (300 μM, black bar). (A) A glycine transport current recorded with 5 mM [Na+]i and 150 mM [Na+]e (striped bar) and (B) a different cell with 50 mM [Na+]i and either 150 mM or 50 mM (shaded bar) [Na+]e. (C) Bar graph of the sustained (black bars) and overshoot (open bars) current amplitudes as a percentage of peak current recorded in various Na+ gradients (n ≥ 10, ANOVA).
