Genetically encoded FRET-based biosensors are increasingly popular and useful tools for examining signaling pathways with high spatial and temporal resolution in living cells. Here, we show basic techniques used to characterize and to validate single-chain, genetically encoded Förster resonance energy transfer (FRET) biosensors of the Rho GTPase-family proteins. Methods described here are generally applicable to other genetically encoded FRET-based biosensors by modifying the tested conditions to include additional/different regulators and inhibitors, as appropriate for the specific protein of interest.
