Voltage-gated Na⁺ current densities and properties in transiently transfected HEK293 cells

The peak Na⁺ current density (I_Na), time to peak, and time course of inactivation properties presented were determined from analyses of records obtained on depolarizations to −20 mV (HP = −120 mV). All values are means ± S.E. The number of cells analyzed is provided in parentheses. *, p < 0.05; **, p < 0.01; ***, p < 0.001 versus Na_V1.5-WT; ##, p < 0.01 versus Na_V1.5-WT + FGF13; one-way ANOVA followed by the Dunnett's post-hoc test.
