Using our robust downstream purification platforms, Bioworkshops can develop an efficient downstream process for most mAbs and many other therapeutic proteins in weeks. We offer the flexibility to transfer, develop and optimize client-specific processes for either monoclonal antibodies and recombinant proteins, and can customize processes to meet clients’ special requests. Our goal for downstream process development is to deliver a robust, scalable and cost-effective purification process through yield optimization and product purity improvement.
