Figure 2From: Oxidative stress promotes autophagic cell death in human neuroblastoma cells with ectopic transfer of mitochondrial PPP2R2B (Bβ2)Differential subcellular localization of ectopic Bβ2 and Bβ1 by confocal image analysis. (A) Cells were immunostained with antiserum against β2 (red) and counter-stained with mitotracker (green) and visualized by confocal microscopy. The merged graph showed that β2 was colocalized as yellow colors at mitochondria in clone Bβ2 #5 and #8. (B) Cells were immunostained with antiserum against β1 (red) and mitotracker as before. The merged graph showed that ectopic β1 can be distributed in cytoplasm in clone Bβ1#1 as compared with SK-N-SH cells. Bar, 20 μm.Back to article page
