HPLC purification of in vitro transcribed long RNA

Weissman, Drew, Pardi, Norbert, Muramatsu, Hiro, Karikó, Katalin·2013·Methods in molecular biology

Abstract

In vitro transcription of DNA with phage RNA polymerases is currently the most efficient method to produce long sequence-specific RNA. While the reaction can yield large quantities of RNA, it contains impurities due to various unwanted activities of the polymerases. Here, we described an easily performed HPLC purification that removes multiple contaminants from in vitro transcribed RNA and is scalable. The purified RNA is translated at much greater levels, especially in primary cells and in vivo. HPLC purification of RNA containing modified nucleosides that suppress RNA-mediated activation of innate immune sensors leads to a non-immunogenic RNA with superior translational capacity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
