Figure 3. Inhibition of Kv1 potassium channel activity by LmKTT-1a.

(A) Current traces of the Kv1.1 channel in the absence (control) or presence of 1 µM LmKTT-1a. (B) Current traces of the Kv1.2 channel in the absence (control) or presence of 1 µM LmKTT-1a. (C) Current traces of the Kv1.3 channel in the absence (control) or presence of 1 µM LmKTT-1a. (D) Concentration-dependent inhibition of Kv1.3 channel currents by LmKTT-1a. Data represent the mean ± S.D. of at least three experiments.
