Product description
The fluorescent dye azides react with alkynes via a copper-catalyzed click reaction (CuAAC). This click chemistry is increasingly being used in a variety of biological applications. XFD488 azide has the same chemical structure to Alexa Fluor® 488 azide (Alexa Fluor® is the Trademark of ThermoFisher Scientific). XFD488 azide is reactive with terminal alkynes via a copper-catalyzed click reaction as a bio-orthogonal or biologically unique hapten for use in applications requiring signal amplification.
