XFD488 amine *Same Structure to Alexa Fluor(TM) 488 amine*

Molecular weight: 719.83. Excitation (nm): 499. Emission (nm): 520. Extinction coefficient (cm-1 M-1): 73000. Quantum yield: 0.92. Correction factor (280 nm): 0.11. XFD488 amine is the same molecule to Alexa Fluor(R) 488 C5 amine. The fluorescent dye amines are reactive molecules that can be used to add a fluorescent label to biomolecules containing a carbonyl group. XFD488 amine reacts with carboxylic acids, aldehydes and ketones. It is a very useful building block for developing XFD488 probes.
