Properties of average-conductance cationic channels that mediate cholinergic excitation of guinea-pig ileum myocytes under conditions close to the physiological norm


The properties of cationic channels of an average unitary conductance were studied in guinea-pig ileum smooth muscle cells using a patch-clamp technique in the outside-out configuration. Cationic channels were activated by addition of 200 µM GTPγS to an intrapipette solution, which resulted in stable activation of G proteins. The replacement of external… (More)
