The mammalian protein expression system is suitable for researchers requiring in vitro recombinant expression of proteins in their native conformation, including modifications such as glycosylation and phosphorylation. Utilizing this system combined with high-density fermentation techniques, our scientists have achieved recombinant antibody expression levels up to 6.3 g/L, making it ideal for the high-level expression of recombinant monoclonal antibody drugs. Our cell culture personnel are all trained under strict GMP and quality control systems, ensuring traceable documentation for Protein Expression and Production.
We have established a comprehensive Recombinant Protein Mammalian Expression System, including but not limited to FreeStyle 293-F, Expi293-F, ExpiCHO-K1, and ExpiCHO-S cell lines. Combined with our proprietary high-expression vectors, featuring CMV promoters and optimized secretion signal peptide sequences, we can offer clients higher expression levels of recombinant proteins through Mammalian Cell Expression and Production. With the use of purification resins and equipment provided by GE, large-scale fermentation, and a single-use cell culture factory for Protein Expression and Production, we can deliver high-quality recombinant proteins in batches. This technical platform enables fermentation and transfection to be completed in one step, significantly shortening the production timeline.
