Figure 3. Dependence of inward-rectifier Cl− currents on inhibition by Zn2+ and Cd2+.
Representative recordings; voltage protocol as in Figure 2. All effects of Zn2+ and Cd2+ were reversible. A, The inhibition of the current at −100 mV by 50 µM Zn2+. B, The inhibition of the current at −100 mV by 500 µM Cd2+.
