The use of in-line Raman spectroscopy as an in-line process analytical technology (PAT), in the biotechnology industry, has matured over the past decade from a technology with promise to a standard tool for real-time, continuous monitoring of cell culture processes. There is an ever-growing body of work demonstrating successful application from metabolite and product quality monitoring to process control in both process development and GMP manufacturing environments. This is due, in part, to advances in technology robustness, user- and integration-interfaces, improved sensitivity, and fluorescence rejection. Organizations are now faced with the difficult task of best leveraging these tools and extracting the most value from them. Thus, defining and executing Raman program strategy is critical to the technology’s long-term success and sustainability.
This presentation will describe Biogen’s past efforts and strategic direction as it relates to in-line Raman spectroscopy for cell culture operations and how we intend to leverage its capability beyond metabolite monitoring and glucose feedback control to become an essential element of our Advanced Process Control efforts.
