工作溶液配制

Rhod-4 NW工作溶液：将20 µL Rhod-4 NW储备溶液加入10 mL 1X分析缓冲液中，并充分混合。 注意：该工作溶液在室温下至少可稳定2小时。

实验步骤

1.将100 µL /孔（96孔板）或25 µL /孔（384孔板）的Rhod-4 NW染料加载溶液添加到细胞板中。

2.在细胞培养箱中将染料加载板孵育30分钟，然后在室温下再孵育30分钟。 注意：如果测定需要37℃，请立即进行实验，而无需进一步室温孵育。 注意：如果细胞在室温下能长时间正常工作，请在室温下孵育细胞板1-2小时。
 
3.准备并添加HHBS或所需缓冲液的复合板。

4.通过检测Ex / Em = 540/590 nm的荧光强度运行钙通量检测。
