Live or Dead 细胞活性检测试剂盒是美国AAT Bioquest生产的细胞活性检测试剂盒,此 Live or Dead 细胞活力检测试剂盒使用两种荧光指示剂:用于标记活细胞的 Cellbrite Red (Ex/Em = 613/631 nm) 和细胞不可渗透的 DNA 结合染料 Nuclear Blue DCS1 (Ex/Em = 360 nm) /450 nm)用于标记膜受损的死细胞。在黑色板中生长的细胞可以在不到两小时内进行染色和定量。该测定比其他活力测定更稳定、更准确。它可以轻松适应各种荧光平台,例如微孔板测定、荧光显微镜和流式细胞术。该试剂盒提供了所有必要的组件以及优化的检测方案。它适用于增殖和非增殖细胞(悬浮细胞或贴壁细胞)。百萤生物是AAT Bioquest的中国代理商,为您提供优质的Live or Dead 细胞活性检测试剂盒。

样品实验方案
简要概述
1.用测试化合物制备细胞
2.添加染料加工溶液
3.在室温或37°C孵育30分钟至1小时
4.在Ex / Em = 610/650 nm(截止= 630 nm,红色)和Ex / Em = 360/450 nm(截止= 420 nm,蓝色)或在荧光显微镜下观察(Texas red/Cy5通道 活细胞),(DAPI通道 死细胞)
工作溶液配制
将5μL的200X Cellbrite Red(组分A)和5μL的200X Nuclear Blue DCS1(组分C)加入1mL的测定缓冲液(组分B)中并充分混合以制备染料 - 工作溶液。 该染料加工溶液在室温下稳定至少1小时。 注意:由于染色条件可能因细胞类型的不同而异,因此建议单独确定组分A和C的适当浓度。有关细胞样品制备的指南,请点击查看。
操作步骤
1.根据标准方案准备细胞。 注意:我们用星形孢菌素(SS)在37℃下处理HeLa细胞4小时以诱导细胞凋亡。 详细信息请参见图1。
2.用100μL/孔(96孔板)或25μL/孔(384孔板)的染料加工溶液替换生长培养基。
3.将染料加工溶液板在室温或37°C孵育30分钟至1小时,避光。
4.用HHBS,PBS或您选择的缓冲液洗涤细胞两次。
5.向细胞中加入100μL/孔(96孔板)或25μL/孔(384孔板)的测定缓冲液(组分B)。
6.用荧光显微镜监测荧光信号,用德克萨斯红或Cy5过滤器检测活细胞,用DAPI过滤死细胞。 还可以使用荧光酶标仪(底部读取模式)在Ex / Em = 610 / 650nm(截止= 630nm,红色)和Ex / Em = 360 / 450nm(截止= 420nm,蓝色)下分析荧光强度。
数据分析
图1.用Live或Dead 细胞活力测定试剂盒*双荧光*(Cat#22788)标记的HeLa细胞的荧光图像。 将100,000细胞/孔/100μL的HeLa细胞在96孔黑壁/透明底板中接种过夜。 将细胞用0-1μM星形孢菌素(SS)在37℃处理4小时(A-D),或在乙醇(E)中固定,然后与染料加载溶液一起温育1小时。 荧光信号分别使用具有德克萨斯红或Cy5过滤器的荧光显微镜测量活细胞(红色)和用于坏死细胞的DAPI过滤器(蓝色)。(F)使用FlexStation®酶标仪(Molecular Devices)测量相应的荧光信号,底部读数模式为Ex / Em = 610/650(截止= 630nm,红色),Ex / Em = 360/450(截止= 分别为420nm,蓝色)。 |
