Electrical properties of StIr and StI W111C channels in PLM.

aG is the channel conductance, calculated as the average ± SD of the events reported in the histograms of figure 5C.bVrev is the voltage at which no current flows in an experiment in which the membrane separated two solutions containing 100 mM KCl on the cis side and 1 M KCl on the trans side.cP+ and P− represent the permeability of the cation and the anion respectively. The Vrev and P+/P− are the averages of five and two independent determinations for StIr and StI W111C, respectively.dI+ and I- symbolize the current measured at +100 mV and −100 mV, respectively. In this case, at least three independent experiments have been performed and the I+/I- error falls within 10%.er is the radius of the pore estimated from the channel conductance as described in the text.Electrical properties of StIr and StI W111C channels in PLM.
