Tetraethylammonium (TEA +) is widely used for reversible blockade of K channels in many preparations. We noticed that intracellular perfusion of voltage-clamped squid giant axons with a solution containing K + and TEA + irreversibly decreased the potassium current when there was no K + outside. Five minutes of perfusion with 20 …
