Upstream continuous processing: recent advances in production of biopharmaceuticals and challenges in manufacturing.

Abstract in brief

• Recent advances in upstream continuous processing focus on improving the production of biopharmaceuticals like therapeutic proteins, viral vectors, and cell therapies through techniques such as perfusion, which involves maintaining high cell densities in bioreactors.
• Innovations include optimizing operation strategies, enhancing cell density control with feed solutions, and integrating advanced monitoring tools like capacitance sensors and Raman spectroscopy to improve process efficiency and product quality.
• These developments are not only applied to primary production but also extend to other upstream processes like cell bank preparation and seed bioreactor operations, aiming to make biopharmaceutical manufacturing more continuous, efficient, and scalable.]
