(a) Steady state inactivation of Kv4.3 current. Cells were subjected to a conditioning potential of 400 ms duration ranging from −105 to +25 mV (in 10 mV increments) prior to a 300 ms step to +65 mV. (b) Normalized current as a function of conditioning potential. The resultant curve is well fit by a Boltzmann sigmoidal function, with V1/2 of steady state inactivation of −51.3±0.2 mV and slope factor of −7.2±0.2 mV (n=11).
