WHITE PAPERS, APPLICATION NOTES, AND DATA SHEETS
An Introduction to FRET, with an Emphasis on the Optics InvolvedFluorescent Resonant Energy Transfer (FRET) is a process that involves two fluorochromes (molecules that have the potential to fluoresce) with overlapping emission and excitation spectra. FRET is useful in determining intra-molecular and...
