Article Snippet: In this step, to attach a 5′ cap to RNA, 10 mM 3′- O -Me-m 7 GpppG anti-reverse cap analog (ARCA) (New England Biolabs) was added, and then incubated at 37°C for 3 h. To remove plasmid DNA, the reaction mixture was treated with RQ1 RNase-free DNase (Promega) at 37°C for 15 min. Next, polyadenylation of the synthesized RNA was performed in reaction solution containing 1 mM ATP (New England Biolabs), E. coli Poly (A) Polymerase (New England Biolabs), and 4,000 U/mL Murine RNase inhibitor (New England Biolabs) at 37°C for 30 min. Then, 5′ cap- and 3′ poly (A)-attached synthesized RNA was purified using RNA Clean & Concentrator-25 kit (Zymo Research).
