Recently, Sijia Peng et al. (Angewandte Chemie Int. Ed. in English demonstrated) the advantages of single molecule photoactivation FRET (sm-PAFRET) using Abberior CAGE 552 as photo-switchable donor. Unlike conventional smFRET, this novel easy-to-implement technique allows to work close to physiological concentrations revealing new molecular mechanisms in the field of gene expression biology.
