Abstract :

Efficient production of therapeutic protein requires an integrated upstream and downstream process. Further, process analytical techniques (PAT) are utilized to control variations and to modulate flexibility in the system to operate it efficiently. Use of GMP compatible, scalable process as well as genetically stable clones facilitates consistent titers and quality of desired product. Any changes for improving the upstream process which results into higher fermentation/ bioreactor yields are always a challenge for the downstream purification team to follow it through to achieve high product yields. In a unique effort, we have studied and demonstrated that changes in the fermentation at scale up level can be systematically visualized at microscopic level with the help of optimized method of preparation of cells under electron microscopy (EM) techniques. These subtle changes in the fermentation can be then fine-tuned to have higher productivity which is very difficult (if not impossible) to achieve. The study also allowed, quantifying the level of production of inclusion bodies and their densities, and to relate them to number of cells expressing them after induction. A novel method thus allows, better optimized fermentation conditions, for achieving higher titers. Study indicates that availability of genetically stable and robust clone for production of therapeutic protein helps in the integrations.
