Plot of channel P o against time for αγ (A) and αγT with and without 0.1 μM amiloride (B). The data used to generate A was from a patch that contained a single high P o αγ channel. B was generated from data from two separate patches, both containing single αγT channels. P o was measured at 30-s intervals in all three of these representative examples. Mean P o refers to P o measurements averaged over the entire life of the patch.
