使用MitoROS 570分析方案
使用前,在室温下解冻 MitoROS Brite 570。解冻后,短暂离心以收集干燥的沉淀。
概述
在生长培养基中准备细胞。
使用 MitoROS Brite 570 工作溶液对细胞进行染色。
用所需的测试化合物处理细胞。
使用 Cy3 滤光片组或 Ex/Em = 540/590 nm 监测荧光强度。
溶液配制
除非另有说明,所有未使用的储备溶液应分成一次性等份,并在制备后储存在-20°C。避免反复冻融循环
1)MitoROS 570 原液配制
在 DMSO 中制备 5 至 10 mM MitoROS Brite 570原液。
注意:制备一次性等份的 MitoROS Brite 570 原液并储存在 ≤ -20°C 下,避光。避免冻融循环。
2)MitoROS 570 工作溶液配制
用HHBS稀释MitoROS Brite 570 原液,制备 5 至 10 μM MitoROS Brite 570 工作溶液。
注意:为了获得效果,请在制备后几小时内使用该溶液。
注意:用箔纸覆盖工作溶液或将其存放在黑暗的地方,以避光。
操作步骤
1.根据需要将细胞铺在 96 孔黑色透明底板中。
2.将 100 µL MitoROS Brite 570 工作溶液添加到细胞中。
3.将细胞在 37°C 避光条件下孵育 30 至 60 分钟。
注意:MitoROS Brite 570 的浓度和孵育时间可能因不同细胞系而异。您可能需要测试不同的浓度以确定条件。
4.除去染料工作溶液并用 HHBS 缓冲液洗涤细胞两次。
5.根据需要处理细胞。
6.去除处理并用 HHBS 缓冲液洗涤细胞两次。
7.添加 HHBS 缓冲液并使用带有 Cy3 滤光片组的荧光显微镜检测细胞荧光。
