Abstract
A linear relationship was found between the antibody production rate (q mAb) and the glucose and lactate consumption rate (q GL) in Chinese hamster ovary cells. Under a series of q mAb-perturbing conditions, q GL was determined and a linear relationship between q mAb and q GL was further established (R 2 = 0.914). Mitochondrial dehydrogenase activity was monitored in all the q mAb-perturbing conditions and showed a linear correlation with q GL (R 2 = 0.874) as well as with q mAb. Taken collectively, our results establish that the metabolic parameter, q GL, is linearly correlated with q mAb; this finding strengthens our current understanding of process optimization for antibody production.
