Scalable mammalian process development covering upstream, downstream and seamless GMP transfer

Turn your molecule into a robust, scalable, and compliant manufacturing process. At 53Biologics, we design and optimize mammalian processes on CHO and HEK293 platforms—from early feasibility through engineering runs—so you can achieve the right balance of yield, cost, robustness, operability, and scalability while aligning to current GMP expectations.

How Our Process Development De-risks Scale-Up

We standardize the journey from first expression to clinical supply with a risk-based, QbD approach. That means structured host selection and clone assessment (productivity, stability, product quality), media/feed optimization, and a bioreactor strategy tailored to the modality (batch, fed-batch, or perfusion). In parallel, we design the downstream train—capture, intermediate, polishing, and UF/DF—so yield, purity, and cycle time are optimized together with phase-appropriate analytical packages aligned to ICH expectations.

Our scale-down models mirror GMP unit operations, enabling data-driven Design of Experiments (DoE), clear CPP↔CQA mapping, and the definition of an evidence-based control strategy with IPCs/PAT where appropriate. The result is a process that transfers cleanly into manufacturing—reducing variability, de-risking engineering runs and tech transfer, and ultimately accelerating batch release and regulatory progress.
