XFD647 Azide

Correction Factor (280 nm): 0.03. Correction Factor (565 nm): 0.1109. Extinction coefficient (cm -1 M -1): 270000. Excitation (nm): 650. Emission (nm): 671 Quantum yield 0.33. XFD647 is manufactured by AAT Bioquest, and it has the same chemical structure of Alexa Fluor(R) 647 (Alexa Fluor(R) is the trademark of ThermoFisher). It is a bright deep red fluorescent dye. XFD647 dye is water soluble and pH-insensitive from pH 4 to pH 10. XFD647 azide is used for conjugation with a biological molecule that contains an alkyne via the click chemistry. It provides a convenient way to install the fluorophore of Alexa Fluor(R) 647 into a biological molecule that lacks alkyne and azide groups.
