Purification of Monoclonal Antibodies using CIM® Affinity Columns

A large number of diagnostics and several therapeutic monoclonal antibodies (mAbs) have been approved worldwide and many more are expected to be approved and licensed in the near future. The reality and the fact that purification or downstream processing can contribute up to 80% of the total production costs of a biopharmaceutical, enhance the need for efficient purification methods. Liquid chromatography provide high level of purity required for human use, increases productivity and has therfore become the method of choice for purification of biopharmaceuticals.

Purification of mAbs can be achieved by a number of chromatographic methods, Protein A and Protein G affinity chromatography being especially powerful enabling high product purity with single chromatographic step.
