Moving a mammalian cell culture process from shake flask to bioreactor is more than a scale-up exercise. Each transition introduces new challenges in oxygen transfer, pH control, CO₂ management, mixing, and data reproducibility. This practical guide explores the key stages of cell culture process development, explains why process transfer often fails, and shows how integrated bioreactor control and data management help create scalable, reproducible processes from screening through scale-up.

Feeding strategy is one of the most influential variables in any bioprocess. Whether you’re working with bacterial, yeast, fungal, or mammalian cell cultures, how you supply nutrients affects everything from growth rates and yields to oxygen demand and product quality. The choice between batch, fed-batch, and continuous culture depends on your organism, application, and production goals. Fortunately, modern bioreactor systems like those from INFORS HT make it easy to implement any of these strategies at lab or pilot scale.
