CaptureSelect purification products enable the efficient capture of therapeutic proteins from any feed stream, thereby helping reduce the number of process steps, increase yield, as well as provide a platform approach for purifying any target biotherapeutic.

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.
