We are interested in examining protein-protein interactions in the plane
of the membrane using FRET and wonder if anyone out there has any
experience with this technique. The plan is to label proteins indirectly
via a Fab or IgG to which has been added a donor or acceptor. The
classic D/A pair seems to be FITC/TRITC, but we may try Cy3/Cy5.
