Dear All
I am looking for a dye, for conjugation to protein, with an absorption
wavelength close to 700nm.  Molecular Probes longest wavelength dye only
goes to 680nm.  It is to act as an acceptor in a FRET measurement so does
not need to be fluorescent.  are there any other sources you could
recommend?

Many thanks
