Basal layers of the rabbit corneal epithelium contain a large-conductance potassium ion (K+) selective channel (160-170 pS in 150 mM KCl). This channel previously was shown to be blocked by cesium and barium ions applied to its outer surface. By direct patch clamp experiments, it is shown that the channel also is blocked by quinidine in the 0.1-1 mM range… CONTINUE READING
