Figure 7. Effects of Zn2+ on the quasi–steady state activation curve of the slow gate. (A) Family of current traces elicited at 0, 10, and 100 μM Zn2+ with a voltage protocol shown on top. All traces were from the same oocyte at 24.0°C. The membrane potential was first held at −30 mV for the slow gating to reach steady state before each experiment started. Horizontal dotted lines indicate level of zero current. (B) Quasi–steady state activation curves at various Zn2+ concentrations from the experiment shown in A. The current amplitudes were measured at the vertical dotted line shown in B. □, ○, and ▵ represent control, 10, and 100 μM Zn2+, respectively. (C) Averaged quasi–steady state activation curves at 19.8, 24.0, and 28.3°C. Symbols are as those in B (n = 3–5).
