Hydrogen peroxide (H₂O₂) is both a source of oxidative damage and a signaling molecule. This protocol describes how to measure mitochondrial H₂O₂ using mitochondria-targeted HyPer7 (mtHyPer7), a genetically encoded ratiometric biosensor, in living yeast. It details how to optimize imaging conditions and perform quantitative cellular and subcellular analysis using freely available software.
