Figure 4. . IRK1 currents in the presence of three metal ion chelators. (A) Current records collected from the same patch in the presence of intracellular EDTA, EGTA, or CDTA, each at 5 mM. Phosphate was used to buffer pH. (B) Normalized I-V curves in the presence of the metal ion chelators. All data points are mean ± SEM (n = 5).
