Inhibiting effect of peptide KTX-Sp4 on exogenous Kv1.x channels. ac Current traces in the absence (control) or presence of KTX-Sp4 on Kv1.1, Kv1.2 and Kv1.3 channels: a 1 μM KTX-Sp4 on Kv1.1, b 1 μM KTX-Sp4 on Kv1.2, c 100 nM KTX-Sp4 on Kv1.3. d Average normalized current inhibition by various concentrations of KTX-Sp4 for Kv1.1, Kv1.2 and Kv1.3 channels, as indicated. Data represent mean ± SE of at least five experiments
