Paragon partners with like-minded innovative organizations that are at the pinnacle of their respective fields. Every partnership is different, but all are grounded in exceptional quality, scientific expertise and an exceptional product.

The CAP®GT expression system is precisely tailored for gene therapy production while the CAP®Go is engineered for glycoproteins.


CAP®GT cells propagate a broad spectrum of viral species supporting lentiviral (LV), adenoviral (AV) and adeno-associated viral (AAV) vectors. Paragon and CEVEC have co-developed a scalable clinical production process for AAV gene therapy vectors based on the CAP®GT expression system.


CAP®GO cells have been used to produce glycol-optimized proteins ranging from virus envelope proteins to cytokines and antibodies. In partnership with CEVEC, Paragon increased traditionally low titer recombinant proteins to exhibit authentic glycosylation and enhanced product quality.
