Figure 3. Design of circular RNAs and their translation in rabbit reticulocyte lysate (RRL).
(A) Schematic representation of the circular RNAs used in this study. The grey dashed line represents the point of ligation of the linear RNA to form a circle. (B) Nucleotide sequence of 4× FLAG circular RNA. The first nucleotide, G, is linked with the last nucleotide, U, in this context. Sequences of the other RNAs are shown in Supplementary Table S1. (C) Western blot analysis of the translation reaction in RRL. The three circular RNAs and their linear precursors (1 μg) were incubated at 30 °C overnight in a 25 μL reaction.
