Large-scale production of murine monoclonal antibodies using hollow fiber bioreactors.
We have produced large quantities of murine monoclonal antibodies for in vivo human clinical trials using hollow fiber bioreactors (HFBRs). Thirty-three different hybridoma cell lines have been evaluated in various HFBR systems. Monoclonal antibody (Ab) productivity is highly dependent on the intrinsic secretory rate of each cell line. Other factors that affect Ab production include capillary membrane molecular weight cutoff, and HFBR design. Studies comparing HFBRs to static and suspension culture systems revealed similar Ab productivity. An advantage of the HFBR is that the Ab is concentrated in the extracapillary space, simplifying downstream processing.
