| | These sets are designed for Fluorescent Resonant Energy Transfer, a technique for determining distance in a sample. FRET using GFP spectral mutants provides the ability to localise and monitor ion-binding and molecular protein-protein interactions in living cells. We offer sets for ratio-metric measurement of CFP/YFP, BFP/GFP, and GFP/DsRed FRET emission and are continuing development of the FRET filter sets for emerging applications.
