Figure 1. Experimental Kv4.3 current.

Figure 1

A, experimental traces of Kv4.3 current recorded using a holding potential of −90 mV and a series of 1000 ms depolarizing pulses from −120 to +50 mV in 10 mV steps at an extracellular K+ concentration of 2 mm using the cut-open oocyte voltage clamp technique. Inset, voltage clamp protocol, used for generation of IKv4.3 traces. B, comparison of the time course of experimental IKv4.3 at depolarization to +50 mV (10 ms pulse) and fitting by function fa(t) =C(1 − exp[−t/τact])n, where n is varied from 1 to 5. In the cases of n = 4 and n = 5, the function fa(t) gave the best fit to the experimental data.
