Figure 2. — Effect of different metal ions on G551D-CFTR and WT-CFTR currents. (A) 10 μM Cd²⁺ and 10 μM Zn²⁺ potentiate G551D-CFTR ATP-independent currents, but 1 mM Ca²⁺ and 10 μM Ni²⁺ have little effect on the currents. (B) WT-CFTR currents are not affected by any of these cations. Dashed lines in all figures represent the baseline.
