An Introduction to FRET, with an Emphasis on the Optics Involved
Fluorescent 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 intermolecular reactions both spatially and temporally. It can be used to follow and record the interactions of proteins, enzymes, DNA, and RNA well below the 200 nanometer (10-9 meter) resolution limit of the optical microscope at its highest magnification and...
Filter Sets for Imaging DsRed (Red Fluorescent Protein)
The new red fluorescent protein, DsRed, from Clontech can be viewed, and imaged, with a variety of filter sets due to its broad absorption and emission spectra. Using HeLa cells transfected with the DsRed protein, kindly provided by Clontech, we obtained excellent images with either the HQ TRITC/Cy3™ ( 41002c or 41002b) cubes or the HQ Texas Red™ set (41004). We also found that a custom set we have made for several researchers worked very well, as did the Phycoerythrin set (41003).
