Mitochondrial function, a key indicator of cell health, can be assessed through monitoring changes in mitochondrial membrane potential (MMP). Cationic fluorescent dyes are commonly used tools to assess MMP. We used a water-soluble mitochondrial membrane potential indicator (m-MPI) to detect changes in MMP in various types of cells, such as HepG2, HepaRG, and AC16 cells. A homogenous cell-based MMP assay has been optimized and performed in a 1536-well plate format, which can be used to screen several compound libraries for mitochondrial toxicity by evaluating the effects of chemical compounds on MMP.
线粒体功能是细胞健康的一个关键指标，可以通过监测线粒体膜电位（MMP）的变化来评估。阳离子荧光染料是常用的评估 MMP 的工具。我们使用一种水溶性的线粒体膜电位指示剂（m-MPI）来检测各种类型的细胞（如 HepG2、HepaRG 和 AC16 细胞）中 MMP 的变化。我们已经优化了基于细胞的均相 MMP 测定法，并在 1536 孔板格式中进行了测试，该方法可用于通过评估化合物对 MMP 的影响来筛选几种化合物库的线粒体毒性。
