AN INTEGRATED CELL CULTURE-PROTEIN PURIFICATION SYSTEM FOR THE AUTOMATED PRODUCTION AND PURIFICATION OF CELL CULTURE PRODUCTS

摘要

An integrated cell culture-protein purification system has been developed for the continuous, automated production of pure cell culture protein products. The instrument comprises a bioreactor subunit (2) having a hollow fiber bioreactor to culture and maintain cells which secrete the desired product into the cell culture medium. The culture medium is circulated through a purification cartridge (4) which adsorbs the desired product. The system is capable of continuously removing the product from the culture medium by immunoaffinity adsorption and pure product is then recovered. The product can also be recovered automatically in a discontinuous operation from the spent culture medium by either affinity, ion exchange, or hydrophobic purification techniques. The integrated system allows continuous production of high-quality pure proteins from cell culture.
