Custom mRNA


OZ Biosciences offers mRNAs that mimic fully processed mature mRNAs.

These mRNAs are stabilized with 5’ Cap 1 structure and 3’ poly(A) tail and are optimized to yield improved stability & performance.

They are modified with 5-methoxyuridine (5moU replaces U) to reduce innate immune responses. We also offer unmodified mRNAs.

4 categories of mRNAs:

Custom mRNA Synthesis Service

Pick any synthetic mRNA of interest with custom modifications.

With over 15 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.

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.


Our 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.
