Custom mRNA Synthesis

With the development of in vitro transcription (IVT) methods, messenger ribonucleotides (mRNA) synthesis has become an emerging class of gene therapy. Serving as the molecular bridge between DNA and proteins, mRNAs and their in vitro transcription technology enable the concept of nucleic acid-encoded proteins for research and therapeutic purposes. The transient nature of mRNA activity also offers an alternative approach to gene editing and gene therapy for delivering genetic information into cells.

To support mRNA research and therapeutic applications, Azenta offers gene synthesis and custom mRNA synthesis with industry-leading project completion time, a wide range of deliverables, and best-in-class quality.

Applications of Synthetic mRNA

Therapeutic Development: Treat diseases of protein expression and cellular function without gene editing
Cancer Research: Express tumor antigens or chimeric antigen receptors (CARs) to investigate cancer treatment and response.
CRISPR/Gene Editing: Create targeting mRNA sequences for delivery of CRISPR/Cas9 and other gene editing platforms.
Antibody Development: Translate antibodies in vivo from encoded mRNA instead of from monoclonal production.

How do you synthesize mRNA?

Synthetic mRNA comes from a template nucleotide sequence of DNA. The process starts with codon optimization of this sequence for optimal transcription. The gene is synthesized, cloned into a vector, and verified by Sanger sequencing. The plasmid DNA is then amplified, target mRNA sequence linearized, and used as a template for in vitro transcription.

Featured Application: mRNA Therapeutic Development

With the critical role of mRNA vaccines in global pandemic response to COVID-19, mRNA synthesis technology has strengthened its status as an important technique in therapeutic development. Sequence accuracy of the template plasmid and the quality of IVT mRNAs are two crucial factors in determining the success of downstream lead generation and characterization. A foundational expertise in gene synthesis accommodates a range of mRNA complexities (5’ cap and poly A tail) to achieve optimal protein expression and generate 100% sequence-verified plasmid constructs.

  1. Pseudouridine is a common RNA modification to replace uridine in IVT mRNA. It has been demonstrated to enhance RNA stability and decrease anti-RNA immune response.
  2. Agilent 2100 Bioanalyzer utilizes LabChip technology to automate the measurement of both the concentration and the integrity/purity of mRNA samples.

Tech Note | High-Fidelity Production of In Vitro Transcription Plasmids with Long Poly(A) Sequences

Poly(A) tail sequences can impact the integrity of your mRNA plasmids for in vitro transcription. While longer poly(A) tails have been shown to increase their stability, tails greater than 100 bases are susceptible to truncations. Learn how the proprietary mRNA plasmid preparation protocol from Azenta can help you generate higher yields and preserve poly(A) tails of greater lengths compared to standard protocols for high-fidelity templates in our tech note.
