Following most cell death signals, pro-apoptotic Bcl-2 members as Bax and Bak are activated and oligomerize into the mitochondria outer membrane, triggering its permeabilization and release into the cytosol of soluble apoptogenic factors such as cytochrome c involved in caspase activation. Thus, in many studies focused on apoptosis, cytochrome c release within cells is frequently examined to assess Bax/Bak activation and mitochondrial outer membrane permeabilization. In addition, cytochrome c release can also be investigated in vitro in functional mitochondria that have been isolated from cultured cells, offering a number of advantages. Here, protocols for measuring cytochrome c release from intact cells as well as from isolated mitochondria is detailed. Finally, assays to investigate Bax/Bak activation and olimerization are also presented.
