Fluorescence immunohistochemistry of MitoSox Red (red) was used to measure mitochondrial superoxide levels. JNK inhibition suppressed the mitochondrial superoxide level at 12 h in glutamate-treated HT22 neurons. Mitochondria were stained with Mito-Tracker (green), nuclei were stained with Hoechst 33,342 (blue).
