Using the perforated patch version of whole-cell recording, we have measured currents from isolated frog lens epithelial cells. Three types of currents were seen. A time-independent outwardly rectifying potassium current was identified that sets the resting voltage. This potassium current differs significantly from any of the potassium currents recorded with the whole-cell technique in mammalian lens epithelial cells. In addition to the potassium current, the two other currents present were both outwardly rectifying: one was time-independent while the other showed distinct activation.
我们使用穿孔膜片钳全细胞记录技术，测量了分离的蛙晶状体上皮细胞的电流。观察到三种类型的电流。一种与时间无关的外向整流钾电流被确定，它设定了静息电压。这种钾电流与在哺乳动物晶状体上皮细胞中用全细胞技术记录到的任何一种钾电流都有显著差异。除了钾电流外，另外两种存在的电流都是外向整流的：一种与时间无关，而另一种表现出明显的激活。
