mRNA Manufacturing: Drug Substance Production

mRNA Drug Substance Production

As mRNA programs develop, quantity and quality requirements increase. Aldevron helps you advance to the next stage, where larger lot sizes, increasing levels of quality oversight and lot-to-lot consistency are required.  

mRNA Process Ill 2

Aldevron produces high-quality mRNA to your specifications using scalable and processes capable of delivering milligram to multi-gram quantities. Aldevron can also provide high-quality enzymes and linearized plasmid DNA for your in-house mRNA synthesis requirements. 

Synthesis with In Vitro Transcription (IVT)

We offer IVT enzymes that are qualified both by activity assays and functionally for RNA synthesis. Our IVT enzymes can also be custom manufactured to meet requirements for construct design and formulation in batch sizes ranging from milligram to multigram scale. 


Our flexible platform supports both enzymatic capping and co-capping. During development we study and optimize for nucleotides, reagents and enzymes mixture and process conditions (temp, and incubation period). 


In the final stage of synthesis, the mRNA is purified in steps involving chromatography and ultrafiltration (UF)/diafiltration (DF) to prepare for the formulation stage.

QC Testing

We provide comprehensive testing for critical attributes such as purity, identity, concentration, total residual protein content, residual DNA template, residual endotoxin content and bioburden. Based on the USP recommendations (released in March 2022) and other regulatory guidance, we are dedicated to meet the highest standard for RNA production and provide guidance to qualify material for our clients’ needs.
