Unlocking Unprecedented Protein Expression
At Protheon, we’ve engineered a revolutionary protein expression system powered by proprietary cell lines developed through years of intensive R&D.
Our unique platform delivers unprecedented levels of protein expression, rapid scalability, and robust cost-efficiency—paired with human- and animal-compatible glycosylation, enhanced efficacy, and streamlined purification.
Engineering the Future of Biotherapeutics
We combine cutting-edge synthetic biology, advanced computational modeling, and precision fermentation to drive the scalable development of next-generation nanoparticle vaccines and monoclonal antibodies. These are biotherapeutics that traditional systems often fail to produce at the necessary scale, speed, or affordability.
Our integrated tech stack is designed to accelerate discovery and delivery—meeting global demand for high-performance biopharmaceuticals that serve both human and animal health.
Next-Generation Vaccine Delivery for Broad and Durable Immunity
Our proprietary platform leverages a ubiquitous iron storage protein that self-assembles into a nanoparticle collectively displaying multivalent copies of an antigen. This structured antigen presentation has been shown to induce stronger and broader neutralizing antibody responses compared to conventional monovalent vaccines. Unlike soluble antigens that freely circulate in the body, this nanoparticle technology provides a stable, high-density antigen array, enhancing immune recognition and promoting more robust, durable immune responses, potentially reducing or eliminating the need for frequent booster doses. This next-generation platform supports a rapid and effective approach to vaccine development across a broad spectrum of infectious diseases.
