How to Guarantee Quality at Prosit Sole?

      At Prosit Sole, The three level cell banks were strickly constracted under GMP equivalent condition in pilot facility. All cell banks passed through stability evaluation. The result shows, that after 100 generations of continuous cultivation, the plasmid retention rate is more than 95%, which met the criteria for GMP production.

      Optimization of FermentationProcess:Considering the safety, Prosit Sole  develops a completely inorganic salt based culture medium and antibiotic-free fermentation process. The overall control SOP of seed recovery, seed expansion and fermentation were optimized according to FDA and CFDA’s requirment. The production process is antibiotic free.

Molecure Screening and Optimizing


Interestingly, all four analogs showed potent activity in inducing the expression of the antiviral genes MxA and OAS and two of them, analog-6 and -7, displayed an unexpected high potency that is higher than that of type I IFN (IFN-α2a) . Together, these studies identified two IFN-λ analogs as candidates to be developed as novel antiviral biologics. Keywords: type III interferon, IFN-λ, IL-29, IL-28B, analog, antiviral
