Antibody affinity chromatography

Antibody-based products are a major source of new therapies. Affinity chromatography plays a major role in their production.

Protein A is the most widely used affinity purification step today and the industrial standard for capturing monoclonal antibodies. Protein A media combine high selectivity with high purity in one single step. They permit a generic approach that simplifies process development and supports purification platform development.

The MabSelect™ family is the flagship of GE Healthcare Protein A affinity media.
