MitoSOX Red

MitoSOX Red is a cell-permeable, mitochondria-targeted fluorescent probe specifically oxidized by superoxide, not other ROS/RNS, producing red fluorescence upon binding to mitochondrial nucleic acids. It is widely used for specific superoxide detection in live-cell imaging, both in vitro and in vivo, with applications in oxidative stress research across fields like neurobiology and cardiology.
