8-Azidoadenosine-5'-O-diphosphate sodium

8-Azidoadenosine-5'-O-diphosphate (8-azido-ADP), a clickable variant of the ATP precursor and purinergic receptor ligand ADP, serves as a photoaffinity label for proteins including glutamate dehydrogenase (GDH) isoproteins from bovine brains, as well as eukaryotic translation initiation factor 2 (eIF2) and guanine nucleotide exchange factor (GEF) from rabbit reticulocytes. Radiolabeled versions of this compound facilitate the identification of these protein interactions.
