RESUMO
Recombinant antibodies have become the major growth trends in biotech industry following their success on therapeutic application and good revenue. But the low level of mammalian expression and laggard fermentation process constrained the development of antibody industry in China. The global advances of antibody industry were reviewed, compared the respective advantage between dihydrofolate reductase and glutamine synthetase expression system, continuous perfusion and fed-batch processes were compared. Finally, based on the knowledge and experience of antibody expression and fermentation, the suitable strategy of antibody industrialization, e.g. the fermentation model and scale, should depend on the comprehensive consideration of entrepreneur for the productivity, manufacturing capacity and market revenue. It may be a wise choice to use glutamine synthetase expression system and continuous perfusion process for the need of Chinese antibody industrialization.
