We offer a unique service for the development of product- and/or process-specific affinity solutions tailored to a target protein and its specific requirements.
The custom ligand can be immobilized on a variety of backbones, including POROS resins, and further developed into an affinity resin, which can be used in large-scale processing of biopharmaceuticals.
