Downstream Process Development focuses on the development and optimization of purification processes to efficiently recover therapeutic proteins while maintaining product quality, yield, and process consistency. Protheragen provides comprehensive downstream process development services, including chromatography development, filtration optimization, ultrafiltration/diafiltration process development, process characterization, and technology transfer support for antibody and AOC CDMO programs.
Overview of Antibody & AOC Downstream Process Development
Downstream process development is a critical stage in biologics manufacturing that follows upstream cell culture production and aims to establish robust purification processes for therapeutic proteins. For antibody-based therapeutics, including monoclonal antibodies, bispecific antibodies, and fusion proteins, downstream development typically involves the optimization of capture, intermediate, and polishing chromatography steps, as well as filtration and concentration processes to achieve effective impurity removal and maintain critical quality attributes. A well-defined downstream process enables consistent product quality, improved process efficiency, and successful scale-up from clinical development to commercial manufacturing.
