HIGH DENSITY CULTURE OF HYBRIDOMA CELLS IN A DUAL HOLLOW FIBER BIOREACTOR

Abstract

Hybridoma cells were cultured for two months in the dual hollow fiber bioreactor (DHFBR) which had been successfully used for high cell density cultures of various microbial cells. In batch suspension culture the concentration of monoclonal antibody (Mab) against human Chorionic Gonadotropin (hCG) and the cell density of Alps 25-3 hybridoma cells were obtained in 30 mu g/mL and 2.35 x 10(6) cells/mL, respectively. The continuous culture with DHFBR produced Mab of 100-130 mu g/mL for 30 days and the estimated cell density in the extracapillary space of DHFBR was 1.87 x 10(8) cells/mL based on the antibody production rate. The productivity of Mab was 205 mg/day per litre of the total reactor volume while that of the batch suspension culture was only 10 mg/L day.
