From E. coli to mRNA Drug Substance – Development of Analytical and Purification tools for a scalable mRNA production process

Presenter: Rok Sekirnik

Event: mRNA Therapeutics Summit

Date: July 14, 2021


The recently demonstrated efficacy of mRNA-based Covid-19 vaccines has shown the promise of this therapeutic format, but also highlighted the need for higher efficiency of mRNA production to meet enormous needs for global vaccine supply. Typical mRNA production process involves three key steps: 1) plasmid DNA (pDNA) production in supercoiled (sc) isoform, linearization and purification, 2) in-vitro transcription (IVT) reaction and 3) mRNA purification. Here we present a chromatographic toolbox for integrated mRNA production from pDNA to mRNA purification, including in-process analytics.
