Block of KvLm-evoked ⁸⁶Rb⁺ uptake by TBA, TEA, and DTX. (A) Dose–response curve for TBA-block measured at 20 min. Solid line depicts the fit to normalized ⁸⁶Rb⁺ uptake = (1 + [TBA]/K _d)⁻¹ with a K _d = 43 ± 6 μM (K _d ± SD). (B) Bars represent uptake at 20 min in presence of 10 mM TEA, and 500 nM DTX relative to control (C).
