Fig. 2. Original current traces demonstrating the inhibitory effect of  S (−)-ropivacaine (83 μm) on a family of Kv4.3/KChIP2.2 currents elicited from a holding potential of −80 mV by the activation protocol (  A ), the inactivation protocol (  B ), and the recovery from inactivation protocol (  C ). Shown are control currents, the effect of  S (−)-ropivacaine, and the currents after washout of the drug effect.
