Technology: Achieving Multiplexed FRET

Facebook X LinkedIn Email

Förster resonance energy transfer, or FRET, provides a means to study the temporal dynamics of protein interactions by measuring the transfer of energy between donor and acceptor molecules. Researchers label two molecules of interest with a donor-acceptor pair, and by monitoring the acceptor emission, they can tell when the molecules are in proximity. For the most part, researchers have used only single donor-acceptor pairs in their FRET investigations. The ability to image multiple such pairs has been constrained by the considerable spectral overlap of the commonly used fluorophores,...Read full article
