The quality layer for RNA innovation

Founded in 2021 in Reykjavík, Ternaria Biosciences develops enabling technologies that improve RNA-based therapeutics. Built on our ArtPure™ technology, our enzymes and mRNA solutions are engineered to deliver the accuracy, precision, and consistency that safe, effective RNA therapies demand — translating into fewer side effects and more predictable outcomes for patients.

We focus on the upstream technologies that shape every downstream result. By engineering higher-performing enzymes and optimized mRNA, we help researchers and developers improve yield, reproducibility, and scalability — whether in discovery, process development, or manufacturing.

Our customers span academia, biotechnology, pharmaceutical development, and manufacturing, united by one goal: delivering reproducible and accurate RNA function in cellular context.
