XFD488 azide *Same Structure to Alexa Fluor™ 488 azide*

Product key features

  • Ex/Em: 499/520 nm
  • Extinction coefficient: 71,000 cm-1M-1
  • Reactive Group: Azide
  • Click Chemistry Conjugation: Efficiently and rapidly labels terminal alkynes via CuAAC and copper-free SPAAC
  • Bright and Stable: Offers high fluorescence intensity, photostability, and consistent performance across pH 4—10
  • Hydrophilic: Prevents aggregation and enhances signal clarity for advanced imaging and live-cell applications

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.
