Transportation: at room temperature for up to 3 weeks. Avoid prolonged exposure to light. Desiccate. Excitation Maximum (nm): 628 Emission Maximum (nm): 642BDP 630/650 is a far red emitting, borondipyrromethene based fluorophore. The dye is tuned to match the standard Cy5 channel, and can be used as an alternative to Cyanine5 and sulfo-Cyanine5. Compared to cyanines, BDP 630/650 possesses a longer fluorescence lifetime which is important for fluorescence anisotropy measurements.BDP 630/650 has a brightness similar to cyanines, and an exceptional photostability. This amine derivative is useful for the reaction with electrophiles, and for enzymatic transamination labeling.
