ddATP trisodium  (Synonyms: 2',3'-Dideoxyadenosine 5'-triphosphate trisodium)

ddATP (2',3'-Dideoxyadenosine 5'-triphosphate) trisodium, an active metabolite of 2',3'-dideoxyinosine, is a chain-elongating inhibitor of DNA polymerase. ddATP trisodium can be used for Sanger method for DNA sequencing and research of virus infection^[1][2][4].

ddATP (0.05-50 μM, 30 min) trisodium inhibits adenovirus DNA synthesis in isolated nuclei from adenovirus-infected KB cells^[1].
ddATP (100 μM, 5 h) trisodium reduces the number of γH2A.X foci in the DSB (DNA double-strand breaks) oocytes^[3].
ddATP trisodium inhibits HIV replication by inhibiting HIV reverse transcriptase^[5].
