Effect of BmK I and BmK IT2 on inhibition of open-state inactivation of DRG type sodium channels. a The time constant of open-state inactivation in the absence (n = 10), presence of 400 nM BmK I (n = 10) and in presence of 400 nM BmK I and 400 BmK IT2 (n = 6). b The time constant of open-state inactivation in the absence (n = 9), presence of 400 nM BmK I (n = 5) and in presence of 400 nM BmK I and 400 BmK IT2 (n = 9)
