Optimizing antibody manufacturing processes has gone beyond the first-order goal of achieving elevated protein titers and now also focuses on understanding biologic and manufacturing process variables that define cellular machinery and protein quality. A holistic approach to biotherapeutic manufacturing incorporates several applied disciplines such as biology, engineering, process control, signal processing, and modeling to reduce the “black-box” model of cell- based protein production into an operational design space. This is in line with the US Food and Drug Administration’s quality…
