A method for identifying a selective persistent Na
+
channel blocker by measuring the ability of the blocker to reduce or inhibit a persistent Na
+
current to a greater degree than a transient Na
+
current. Aspects of the present method provide Na
+
depletion/repletion methods for identifying a selective blocker of a persistent Na
+
channel, hyperpolarization methods for identifying a blocker of a persistent Na+ channel, and Na/K ATPase pump inhibitor methods for identifying a selective blocker of a persistent Na
+
channel.
一种通过测量阻断剂降低或抑制持久性 Na + 电流的能力比降低或抑制瞬时 Na + 电流的能力更强来鉴定选择性持久性 Na + 通道阻断剂的方法。 本方法的各个方面提供了用于鉴定持久性 Na + 通道选择性阻滞剂的 Na + 耗尽/补足方法、用于鉴定持久性 Na + 通道阻滞剂的超极化方法和用于鉴定持久性 Na + 通道选择性阻滞剂的 Na/K
