ResumoAbstract Hybridoma batch cultures were extended using feed formulations based on nutrient consumption measured during different batch culture phases when (a) growth but negligible antibody production was taking place; (b) maximum antibody production rate and declining viable cell growth rate were observed. Strategy (a) was the more successful (2.8‐fold compared with 1.8‐fold antibody titer increase) and maintained cell viability for longer. Analysis of the effects of omitting individual amino acids yielded results which were consistent with those from the feeding experiment © 1994 John Wiley & Sons, Inc.
