SMeFM triphosphate is not incorporated into synthesized RNA. (A) In vitro RNA synthesis from vRNPs with SMeFM and SMeFM triphosphate (SMeFM TP). In vitro RNA synthesis assay was performed with SMeFM or SMeFM TP at 30°C for 30 min. Synthesized RNAs were separated by UREA-PAGE. (B) Limited elongation assay with SMeFM TP. In vitro RNA synthesis assay was performed with or without UTP, ATP, or SMeFM. Synthesized RNAs were separated by UREA-PAGE. The expected lengths of limited elongation products without UTP were 12 nt for segments 1, 3, and 7, 13 nt for segment 5, 14 nt for segment 6, 18 nt for segment 4, and 19 nt for segment 2.
