The effects of Na+ removal on pHi in NE-MD cells. a Representative tracing of the pHi changes induced by the reduction of Na+ from the bathing solution and its calibration at the end of the trace. Concentrations of the remaining [Na+] in the bathing solution are indicated at the top (left). Values at the top (right) show pH of the extracellular solutions for the calibrations. b pHi-[Na+] curve. Bars indicate the standard errors. n = 7 each
