Enzymatic synthesis methods for the fluorinated 5'-triphosphate analogues 5F-UTP and 5F-CTP have been developed to facilitate 19F-labeling of RNAs for biophysical studies. HIV-2 TAR RNAs were synthesized using these analogues by in vitro transcription reactions using T7 RNA polymerase. The uniform incorporation of 5F-U or 5F-C analogues into HIV-2 TAR RNA transcripts does not significantly alter the
