  1. ΔΨ (mV) and ΔpH (mV) were determined from radioactive lipophilic cation TPP+ and weak acid DMO distribution between the internal volume of intact cells and the cell medium by the silicone oil-spin method. Values are means (± S.D.) from three experiments, where each determination was done in duplicate.
