XFD488 amine is the same molecule to Alexa Fluor® 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.
