Pedro Escoll

In living cells, monitoring of mitochondrial membrane potential with dyes like TMRM by confocal microscopy (spinning disk) can be a good choice.

For IHC in fixed cells, staining of Cytochrome C can be an option.

Good luck!

Philippe D'Onofrio

Thanks Nicolas! I'm actually also interested in Cytochrome C degradation, do you know if it's possible to see fragments of it resulting from cleavage?
