Extraction-less reverse phase (rp) chromatography of mrna encapsulated in lipid nanoparticles for mrna purity assessment

Abstract

Aspects of the disclosure relate to liquid chromatography (e.g., HPLC) methods which enable identification of one or more target nucleic acids in a mixture (e.g., pharmaceutical composition). The disclosure is based, in part, on methods that allow for addition of pharmaceutical compositions (e.g., lipid-based pharmaceutical compositions) directly onto a chromatographic column without the need for first separating target nucleic acids out of the composition. Accordingly, in some embodiments, methods described by the disclosure are useful for assessing the quality of pharmaceutical preparations comprising nucleic acids.
