Ⅱ　卵母细胞的电生理实验方法　　卵母细胞是研究离子通道结构及其功能较为理想的表达系统。理论上卵母细胞的电生理记录方法与一般细胞基本相似,但仍有其特殊之处。常用方法主要包括双微电极电压钳制记录法、ｃｕｔｏｐｅｎ电压钳制记录法及ｍａｃｒｏｐａｔｃｈ,ｇｉａｎｔ Ⅱ Oocyte electrophysiological experimental method Oocyte is to study the ion channel structure and its function more ideal expression system. Theoretically, the electrophysiological recording method of oocytes is basically similar to that of general cells, but there are still some special features. Common methods include dual microelectrode voltage clamp recording method, cutopen voltage clamp recording method and macropatch, giant
