CFP-YFP FRET biosensors
Construct PatternCFP-YFP FRET biosensors are genetically encoded visible-range reporter constructs used in the cited study to measure RhoA activity and Rac1-GDI binding. In that work, they were combined with a near-infrared Rac1 biosensor to enable parallel imaging of Rho GTPase signaling during optogenetic manipulation of Rac1.
