With over 20 years of nucleic acid delivery expertise, OZ Biosciences is confident in providing you with the best-in-class service for the production of high quality mRNAs.

Our platform can produce custom mRNA according to your needs and preferences. Pick any synthetic mRNA of interest with custom modifications.

Custom mRNA modifications

We are able to synthesise custom mRNAs at microgram to multigram scales, from a few hundred up to several thousand bases, with a wide variety of modifications including 5’ terminal modifications with cap, internal modifications such as 5-methoxyuridine (other modified nucleotides are available) and 3’ modifications such as poly-A tail. Fluorescent labeling with Cy5, Cy3 and other options are also available.

custom mrna synthesis

Our custom mRNA service includes:

  • Synthesis of the gene, cloning and DNA template production
  • mRNA synthesis by in vitro transcription 
  • Purification and quality control

All our mRNAs are purified and checked for their quality. 

Our expert product support team is at your service for your special requests - you are invited to reach out to our experts to discuss your needs.

Custom mRNA F.A.Q

How can I request a quote for custom mRNA synthesis?

You can easily request a quote by filling in our dedicated form available here. If you need further guidance or wish to discuss your project and specific requirements with our technical team, feel free to contact us — we will be happy to arrange a meeting at your convenience.

What are the lead times for custom mRNA orders?

Custom mRNA synthesis from a provided sequence typically takes approximately 6 to 8 weeks. For projects also requiring downstream formulation, such as LNP encapsulation, please refer to our dedicated LNP formulation service for associated timelines.

What is the minimum quantity of mRNA we can synthesize?

The minimum order quantity for custom mRNA synthesis is 0.2 mg. For specific requirements outside this range, please contact us to discuss available options.

Can codon optimization be performed for custom mRNA orders?

Yes. Codon optimization is available for the species of your choice, including human, mouse, and rat. Optimizing codon usage can significantly improve translation efficiency and protein yield in the target organism, and is particularly recommended for constructs intended for in vivo use or when high expression levels are required.

Can I use my own DNA template for custom mRNA synthesis?

When ordering a custom mRNA from OZ Biosciences, you can either:

  • give us the sequence of your gene and we handle the DNA synthesis,
  • or send us your DNA template.

If you choose the second option, your DNA template needs to:

1. Be linearized (or contains a restriction site after the Poly(A) tail

2. Includes a T7 promoter and a Poly(A) tail sequence*

*The Poly(A) tail can be added after in vitro transcription as an additional service (if asbent from DNA template).

3. Be purified (methods of your choice, i.e.) and oberve ratio of A260/A280 and A260/A230 > 1.8

For 1mg of mRNA, we will require ~20µg of purified linear DNA.

For more details, please refer to our DNA plasmid requirement guideline.

What UTR sequences are used in our mRNA constructs?

The 5' and 3' untranslated regions (UTRs) play a critical role in mRNA stability and translational efficiency. Our standard RNAs bear optimized UTR sequences for optimal expression.

What quality controls are performed on our custom mRNA products?

All our custom mRNAs are purified and undergo rigorous quality control before delivery. We offer two levels of QC depending on your requirements:

Standard QC includes:

  • Concentration measurement (spectrophotometry).
  • Purity assessment via 260/280 and 260/230 absorbance ratios.
  • Integrity analysis by agarose gel electrophoresis and HPLC profiling.
  • Sterility testing.

Superior Grade QC includes all Standard QC checks, plus:

  • Endotoxin testing.
  • dsRNA quantification.
  • Protein expression (when possible, i.e. fluo proteins, antibody available.)

Please refer to our mRNA quoting tool to select the QC level that best fits your project requirements.

How is our mRNA packaged, and can it be aliquoted?

By default, 1 mg of mRNA is supplied in a single vial at 1mg/mL. However, aliquoting is available upon request. Simply specify your preferred aliquot size or number of vials when placing your order and we will accommodate your needs.
