Abstract: To gain additional insight into how specific cell organelles may participate in redox signaling, it is essential to have access to tools and methodologies that are suitable to monitor spatio-temporal differences in the levels of different reactive oxygen species (ROS) and the oxidation state of specific redox couples. Over the years, the use of genetically-encoded fluorescent redox indicators with a ratiometric readout has constantly gained in popularity because they can easily be targeted to various subcellular compartments and monitored in real time in single cells. Here we provide step-by-step protocols and tips for the successful use of roGFP2, a redox-sensitive variant of the enhanced green fluorescent protein, to monitor changes in glutathione redox balance and hydrogen peroxide homeostasis in the cytosol, peroxisomes, and mitochondria of mammalian cells.
