Mitochondrial function, a key indicator of cell health, can be assessed by 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 HepG2 cells. A homogenous cell-based MMP assay was optimized and performed in a 1536-well plate format to screen several compound libraries for mitochondrial toxicity by evaluating the effects of chemical compounds on MMP.
