Figure 2From: Differential production of superoxide by neuronal mitochondriaMitochondrial Quantification by MitoTracker Green. Isolated mitochondria preparations were corrected for protein concentration and then treated with MitoTracker Green, which becomes fluorescent in the lipid environment of active mitochondria. Fluorescence is in arbitrary units. Mitochondrial samples from RGC-5 cells, neuroblastoma cells, and cerebral cells exhibited similar fluorescence values, indicating similar amounts of mitochondria per unit protein.Back to article page
