About Us
Who We Are
Sirius Proteins is transforming the landscape of protein production with groundbreaking bacterial expression technology. With a commitment to efficiency, innovation, and cost-effectiveness, we provide large-scale manufacturers across the biotech, health, food, cosmetics, and energy sectors with the tools they need to enhance their protein yields, simplify production processes, and expand their manufacturing potential.
Our patented technology is designed to address the complexities and limitations of traditional protein production, enabling high yields, lower costs, and unprecedented flexibility.

The Problem
Challenges in Protein Production
Many organizations face significant challenges in scaling recombinant protein production due to low yields in bacterial systems, the high costs of using mammalian cells for complex proteins, labor-intensive purification processes, and limitations in producing toxic or complex proteins.
These issues increase costs and slow down time-to-market, hindering efficiency and scalability across industries.
Our Solution
Sirius Proteins offers advanced bacterial expression technology to overcome key production challenges, enabling up to 100-fold increases in protein yields without extra facility space. Our system allows efficient production of complex proteins, like disulphide-bonded antibodies, in E. coli—cutting costs tied to mammalian cells.
We streamline purification by isolating vesicle-packaged proteins directly from culture media and enable safe production of traditionally toxic proteins. With Sirius Proteins, manufacturers gain a more efficient, versatile, and scalable protein production process.
