Abstract: | The fluorescent dye Rhodamine-123, which selectively stains mitochondria depending on the mitochondrial membrane potential, was used with flow cytometry to evaluate alterations in activity of mitochondria isolated from mouse liver. Under in vitro conditions, with succinate and ADP present in the buffer, mitochondrial activity was affected by a variety of metabolic inhibitors that modify membrane potential. These results demonstrate clearly that flow cytometric techniques using Rhodamine-123 can be employed to study activity in isolated mitochondria. |
