Event Overview:

Industrial-scale production of mRNA has taken on renewed importance due to the on-going pandemic. Efficient translation of mRNA to protein depends critically on: (i) 5’-terminal capping, and (ii) 3’ terminal polyadenylation, which can be considered critical quality attributes to be characterized and monitored.

This presentation will show that:

• mRNA capping can be analyzed by LC-MS within 75 minutes by taking advantage of a thermostable enzyme to rapidly liberate 5’ terminal oligonucleotides.
• Certain enzymes commonly used during in vitro transcription can incorporate non-templated nucleotides into both 5’ and 3’ terminal regions.
• Non-templated nucleotides can be considered product-related impurities and can be detected and quantified by LC-MS.

Key Learning Objectives:

• LC-MS is a robust, sensitive and specific technology for quality control of mRNA.
• Workflows for analysis of mRNA 5’ capping and poly-A tailing
• Detection and characterization of product-related impurities stemming from incorporation of non-templated nucleotides

Who Should Attend:

• Biopharmaceutical scientists
• Lab managers
