in vitro AMPylation of proteins[1,2]
in vitro polyadenylation of RNA[3]
The resulting alkyne-functionalized protein[1,2] or RNA[3] can subsequently be processed via Cu(I)-catalyzed (azide-alkyne) click chemistry that offers the choice

  • to introduce a Biotin group for subsequent purification tasks (via Azides of Biotin)
  • to introduce fluorescent group for subsequent microscopic imaging (via Azides of fluorescent dyes)
  • to crosslink the RNA to azide-functionalized biomolecules e.g.proteins
Presolski et al.[4] and Hong et al.[5] 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.
Agonistic ligand, mainly for nucleoside receptor A1
Nucleoside-triphosphates can be converted by different membrane-bound phosphatases into nucleosides acting as nucleoside receptor ligands. In some cases nucleoside phosphates act also directly on nucleoside receptors.

Please note: This compound contains a phosphoramide linkage which is hydrolyzed at pH <7.0.
For preparation of a 10 mM solution use 100 mM buffer (for example: bicarbonate, borate, phosphate and Tris) to prevent degradation at acidic pH.
