Applications:
Incorporation into DNA by PCR with family B polymerases (Pwo, Deep Vent exo^- or KOD XL)^[1,2]
Incorporation into DNA by Primer Extension with family A polymerase Taq and family B polymerases (Pwo, Deep Vent exo^- or KOD XL)^[1]
The resulting ethynyl-functionalized DNA can subsequently be processed via Cu(I)-catalyzed click chemistry that offers the choice

• to introduce a Biotin group (via Azides of Biotin) for subsequent purification tasks
• to introduce fluorescent group (via Azides of fluorescent dyes) for subsequent microscopic imaging
• to crosslink the DNA to Azide-functionalized biomolecules e.g.proteins

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.
