A Systematic Strategy of Cell Culture Media and Feed Development

Development of a high-performance and robust fed-batch process for recombinant Chinese Hamster Ovary (CHO) cell lines presents challenges in light of the diverse nutritional requirements observed with different clonally derived cell lines as well as the varied production phases. To address these challenges, we will discuss an innovative strategy of media, feed, and process development that has been developed at FUJIFILM Diosynth Biotechnologies (FDB). The efficiency and effectiveness of this strategy have been well demonstrated in multiple mAb-producing CHO cell lines at varied scales, with a good balance between product yield and quality.
