Genetically encoded fluorescent H2O2 probes continue to advance the field of redox biology. Here, we compare the previously established peroxiredoxin-based H2O2 probe roGFP2-Tsa2ΔCR with the newly described OxyR-based H2O2 probe HyPer7, using yeast as the model system. Although not as sensitive as roGFP2-Tsa2ΔCR, HyPer7 is much improved relative to earlier HyPer versions, most notably by ratiometric pH stability. The most striking difference between the two probes is the dynamics of intracellular probe reduction. HyPer7 is rapidly
