Description:
F-ara-EdU [(2'S)-2'-deoxy-2'-fluoro-5-ethynyluridine] can be used as a replacement for EdU (5-ethynyl-2'-deoxyuridine) and BrdU (5-bromo-2'-deoxyuridine) to introduce bioorthogonal functional groups into DNA for diverse applications in basic research, biotechnology and drug discovery. Metabolic incorporation of F-ara-EdU into DNA can be detected by using Cu(I)-catalyzed click reaction with fluorescent azides. F-ara-EdU is less toxic than both BrdU and EdU, and it can be detected with greater sensitivity in experiments where long-term cell survival and/or deep-tissue imaging are desired.[1-2]

Presolski et al.[3] and Hong et al.[4] provide a general protocol for Cu(I)-catalyzed click chemistry reactions that may be used as a starting point for the set up and optimization of individual assays.
