Parameters for kinetics of inactivation and recovery from inactivation.

+β1 wild type, statistically significant differences were determined with a one-way ANOVA test followed by a Holm-Sidak test for multiple comparisons (n = 4–9, *P<0.05, **P<0.01, ***P<0.001). The time constants of inactivation were obtained by fitting with single exponential equations, and the time constants of recovery were obtained from fitting with double exponential equations. Each cell was fitted individually and the mean time constants from each group were compared with the Nav1.4
