5-FAM Azide


Click chemistry describes a class of chemical reactions that use bio-orthogonal or biologically unique moieties to label and detect a molecule of interest in mild, aqueous conditions. The click reaction involves a copper-catalyzed triazole formation from an azide and an alkyne. The azide and alkyne moieties can be used interchangeably; either one can be used to tag the molecule of interest, while the other is used for subsequent detection.
The 5-FAM azide  is reactive with terminal alkyne via a copper-catalyzed click reaction that allows the subsequent visualization by fluorescence spectroscopy.


  • Efficiency—the click reaction is complete in less than 1 hour;
  • Specificity—the reaction between the label and detection tag is selective and specific;
  • Stability—the reaction product contains an irreversible, covalent bond;
  • Biologically inert—the components of the reaction do not undergo any side reactions.
