Values are means ± SEM calculated from fits of the data from the
indicated number of individual cells (in parentheses) to the Boltzmann
equation; V1/2 midpoint potential (mV) for
voltage-dependent of activation or inactivation; k , slope factor.
These values pertain to Fig. 3, 5, 6 and supplementary figure 5. Data
were analyzed with Mann-Whitney test.
