Figure 2. Blocking affinity is decreased by external K+. Block was analyzed according to Eq. 3 at extracellular K+ concentrations of 11 and 110 mM for (A) 1 mM Mg2+, (B) 40 mM Na+, and (C) 3 mM TEA+. Typical current traces at two voltages with and without blockers are shown at the top of each panel. Values of Ki(0) increased from 1.6 to 4.2 mM (Mg2+), 117 to 293 mM (Na+), and 1.8 to 5.3 mM (TEA+). No significant changes in zδ were observed for any of the blockers.
