BDP 630/650 is a far red emitting borondipyrromethene based fluorophore for the Cyanine5 channel. Because of its relatively long lifetime of the excited state, this dye is particularly useful for fluorescence lifetime related measurements.
The reactive maleimide moiety allows to attach the dye to thiol groups in biomolecules, especially proteins and peptides.
