Production of in vitro transcription (IVT) templates for mod-mRNA generation was adapted from Warren et al14. Briefly, plasmids used as template for PCR for IVT template preparation were obtained from Addgene: pcDNA3.3_KLF4 (catalog # 26815); pcDNA3.3_OCT4 (catalog # 26816); pcDNA3.3_SOX2 (catalog # 26817); pcDNA3.3_c-MYC (catalog # 26818); pcDNA3.3_LIN28A (catalog # 26819); pcDNA3.3_d2eGFP (catalog # 26821). Additional plasmids with inserts encoding mWasabi, human NANOG, and M3O (pcDNA3.3_mWasabi, pcDNA3.3_NANOG, pcDNA3.3_M3O) used for IVT template preparation were cloned using the following Addgene plasmids: pTEC15 (mWasabi, catalog # 30174); pGEM-NANOG (catalog # 16351); pMXs-hM3O-IP (catalog # 46645). IVT templates were PCR generated using listed plasmids as templates. Forward primer is 5′-TTGGACCCTCGTACAGAAGCTAATACG-3′ and reverse primer used to introduce 120 polyA tail sequence is 5′-TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTCTTCCTACTCAGGCTTTATTCAAAGACCA-3′. These primers were synthesized by Integrated DNA Technologies. Reverse primer was synthesized as Ultramer oligos at a 4 nmol scale.
