in vitro polyadenylation of RNA
2-Ethynyl-labeled adenosine triphosphate (2-EATP) is suitable for in vitro polyadenylation of RNA with recombinant poly(A) polymerase.
The resulting Alkyne-functionalized RNA can subsequently be processed via Cu(I)-catalyzed Azide-Alkyne click
chemistry (CUAAC) that offers the choice
Presolski et al. and Hong et al. 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.
