样品实验方案

简要概述

1. 用测试化合物准备细胞
2. 加入三重荧光工作溶液（100 µL /样品）
3. 在室温或37℃下孵育30-60分钟
4. 用荧光显微镜在FITC通道（凋亡），DAPI通道（坏死）或Texas Red / Cy5通道（健康细胞）处进行分析

 

溶液配制

工作溶液配制

将10 µL的100X Annexin V-iFluor 488偶联物（组分A），5 µL的200X Nuclear Blue DCS1（组分C）和5 µL的200X Cellbrite Red（组分D）添加到1 mL的测定缓冲液（组分B）中 ）。 三重荧光测定溶液在室温下稳定至少1小时。 注意：由于染色条件可能会因细胞类型而异，因此建议分别确定组分A，C和D的适当浓度。

 

实验步骤

1.处理后除去细胞培养基并检测化合物。

2.加入100 µL /孔（96孔板）或50 µL /孔（384孔板）的三重荧光分析溶液。 在避光条件下，于37℃孵育30至60分钟。

3.用HBSS，PBS或自备缓冲液洗涤细胞两次。

4.在带有FITC滤光片的荧光显微镜下，用Annexin V-iFluor 488偶联物分析凋亡细胞。 质膜上的绿色染色（Ex / Em = 494/520 nm）表明膜联蛋白V-iFluor 488缀合物与细胞表面的PS结合。 使用荧光显微镜用DAPI滤光片（Ex / Em = 350/461 nm）检测坏死的荧光强度，使用Texas Red或Cy5滤光片（Ex / Em = 613/631 nm）检测活细胞的荧光强度。
