Kritsiligkou et al. have developed a yeast library in which every protein is equipped with its own proximal H2O2 probe. Use of this library reveals redox differences and changes on the scale of individual protein complexes, invisible to H2O2 probes that sample a whole membrane-bounded compartment by random diffusion.
Yeast library strains are available from the first author upon request.
