Fig. 3. Dependence of TEP oscillations on [Cl-]p. Eight tubules were exposed to varying concentrations of Cl- (in mmoll-1; indicated at top of panels) in the peritubular bath; seven of these tubules exhibited TEP oscillations. In one tubule (A), the oscillations disappeared at 55.5mmoll-1 Cl- and reappeared as [Cl-]p was reduced further. In the six other tubules, the amplitude of the oscillations decreased as [Cl-]p decreased (B). (C) Averaged data from the latter six tubules only. Values are means ± S.E.M.
