Engineering quality into mRNA performance

Ternaria designs the quality layer for therapeutic mRNA. How an mRNA is designed and produced shapes how it performs in the body, from potency to safety to reproducibility.

Why it matters

RNA performance is shaped long before it reaches the cell. RNA polymerase purity, IVT performance and construct design work together to determine RNA quality, translation, potency and safety.

What we do

We bring RNA design, enzyme innovation, and production together. We develop and manufacture ultra-pure RNA polymerases and purpose-built mRNA, powered by our proprietary platform that enables the next generation of RNA technologies.

Who we serve

We work with teams pushing RNA further, from academic research and therapeutic development to pharma R&D, manufacturing partners and CDMOs, across vaccines, oncology and rare disease.

From your goal to your therapeutic solution

Start

Your goal

The therapeutic outcome the mRNA must deliver

  • Target tissue and cell type
  • Protein or antigen to express
  • Combination of delivery system
  • Indication and modality
Produce

ArtPure™

Optimal IVT reaction with proprietary enzymes

  • >99% pure, animal-origin-free RNA polymerases
  • Higher mRNA yield, less dsRNA by-products
  • Increased protein translation in vivo
  • Novel enzymes powered by ArtZymeAI™ where a construct demands it
