Figure 7. Zn2+ strongly augmented the amplitude and prolonged the decay of currents induced by brief puffer application of ATP.
A, fast ATP current elicited by 10 ms pulse of pressure-applied 1 mm ATP in control (a) and in the presence of 30 μm Zn2+ (b). B, histograms showing potentiating action of 30 μm Zn2+ on the amplitude or decay of ATP-induced currents (n = 4). *P < 0.05.
