Monitoring cytosolic H2O2 fluctuations arising from altered plasma membrane gradients or from mitochondrial activity
Abstract
Reliable methods of measuring intracellular H2O2 fluctuations are necessary to advance redox biology. Here the authors design a H2O2 sensor based on the fission yeast peroxiredoxin Tpx1 to sense nanomolar fluctuations of intracellular H2O2 in response to genetic and environmental perturbations.
