Mammalian cells are currently the primary system for the production of recombinant proteins for clinical applications due to their capability for proper protein folding, assembly and post-translational modification. These mechanisms ensure the quality and efficacy of protein of interest being produced compared to bacterial systems.

Recently, the productivity in the range of multi-gram per litre has been achieved in mammalian cells cultivate in bioreactors as a result of improvements in media formulation, clonal selection and cell line development. Cell line development services offered by the Protein Science team at Inno Biologics cover molecular biology, cell culture, process development, protein expression and verification.
