Efficient Strategies to Deliver Reliable and High Quality Biomanufacturing Processes Through Optimization of Cell Culture Media, Feeds, and Process Parameters

Development of a reliable and high quality biomanufacturing process for recombinant CHO cell lines presents challenges from diverse nutritional requirements observed with different clonally derived cell lines, and variable response to process operating ranges. To address these challenges, we will discuss efficient approaches to optimize CHO cell culture media, feeds, and process parameters within FUJIFILM Diosynth Biotechnologies (FDB). Also discussed is FDB’s new ApolloTM CHO expression system, a cornerstone of process scale-up efficiency offering robust gene expression in a platform…

Evaluation of Rapid Quantitation Methods for Titer, HCP and ProA By Gyrolab Platform During In-Process Development

Getting biopharmaceuticals through development and into clinical proof-of-concept fast and efficiently is critical for success in our industry. Therefore, high-throughput upstream and downstream process development approaches are increasingly being implemented. Hence, innovative and high-throughput analytical technologies are needed to support rapid process development. A novel automated analytical platform-Gyrolab xP workstation was investigated for the analysis of IgG titer, Host Cell Protein (HCP) and leached ProA during in-process development. The assays are automated within a Gyrolab compact disc (CD) containing affinity-capture…

Maximizing Protein Expression in CHO Suspension Cells Through Transient Transfection

Transient transfection in mammalian cell lines provides an avenue for researchers to bridge the development bottleneck and shorten the time to usable protein. The method also maintains post translational modifications crucial for biotherapeutic function. Chinese Hamster Ovary (CHO) suspension cells are especially suited for high yield production of recombinant proteins, despite being refractory to commonly used transfection methods (e.g. 25kDa linear PEI). Mirus Bio has developed a more effective alternative, the TransIT-PRO® Transfection Kit. Transfection efficiencies are affected by many…
