产品概述

我们的Cell Meter 检测试剂盒是一套用于检测细胞生存力的工具,可以使用多种参数。该特定试剂盒旨在同时检测凋亡,坏死和健康细胞。细胞凋亡是一种主动的程序化的细胞自发解体过程,可避免引起炎症。在凋亡中,磷脂酰丝氨酸(PS)被转移到质膜的外部小叶。作为细胞凋亡初始/中间阶段的通用指标,在观察形态变化之前,可以检测到磷脂酰丝氨酸在细胞表面的出现。 PS指示剂Annexin V-iFluor 488共轭物与膜PS结合后具有绿色荧光。膜不透性的Nuclear Blue DCS1(Ex / Em = 350/461 nm)标记细胞核的能力证明,质膜完整性的丧失代表了显示凋亡和坏死晚期的直接方法。此外,该试剂盒还提供了活细胞标记染料Cellbrite Red(Ex / Em = 613/631 nm),用于标记非凋亡健康细胞。该试剂盒经过优化,可通过荧光显微镜同时检测细胞凋亡(绿色),坏死(蓝色和/或绿色)和健康细胞(红色)。百萤生物是AAT Bioquest的中国代理商,为您提供优质的Cell Meter 细胞凋亡和细胞坏死检测试剂盒。

实验方案

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。
