Figure 6. The effect of oligomycin B on Ca2+ transients.
A, oligomycin (5 μM) did not alter the peak [Ca2+]c transient markedly in response to a depolarizing pulse to 0 mV (holding pulse - 70) or slow the rate of decline of the Ca2+ transient following repolarization. B shows superimposed traces. C, summary of the rates of decline of Ca2+ with time in control and oligomycin B-treated cells (n = 4).
