F-ara-EdU

F-ara-EdU is a probe for DNA synthesis that is less toxic compared to 5-ethynyl-2′-deoxyuridine (EdU) and BrdU. Ideally suited for metabolic DNA labeling experiments where long-term cell survival and/or deep-tissue imaging are desired. The alkyne handler can be used for subsequent ligation to azide-containing molecules through a highly efficient click chemistry reaction.
