On paper, scaling a bioprocess from a 10-L to a 100-L to a 2,000-L bioreactor may seem like a straightforward math problem that could be solved by software. In practice, however, the exercise relies on a complex set of biological, chemical, and engineering assumptions; on maintenance of healthy cell cultures; and on management of equipment and analytics while adjusting to each increase in scale (1). Process development and quality control groups need to monitor how scale-up might affect critical quality…
