Methods and Compositions for Messenger RNA Purification

Abstract:

The present invention provides, among other things, methods for purifying mRNA, which involves removing impurities from a messenger RNA preparation synthesized by large scale in vitro transcription process (IVT), by precipitating the IVT-synthesized mRNA in a buffer comprising a denaturing salt in combination with a reducing agent, followed by capturing the precipitated mRNA and dissolving the captured mRNA into a solution to obtain purified mRNA.
