Optimizing high throughput antibody purification by using continuous chromatography media.

The ability to engineer monoclonal antibodies (mAbs) with high specificity made mAbs the fastest growing segment in the drug market. mAbs represent 8 of the top 20 selling drugs with combined sales of more than 57 billion US$ per year. The ability to purify large numbers of mAbs with sufficient yields for initial screening campaigns has direct impact on the timelines of a project. Automated liquid handling (ALH)-based mAb purification platforms have been used to facilitate the production of large numbers of mAbs. However, the ongoing pressure to de-risk potential lead molecules at an early development stage by including bio-physical characterization of mAbs has further increased the demand to produce sufficient quantities from limited sample volumes. A bottleneck so far has been the limited dynamic binding capacity of these systems, which is partly due to the binding properties of commonly used Protein A affinity matrices. The present publication suggests that by using a Protein A matrix optimized for continuous chromatography applications the yields of ALH-based but also standard lab-scale mAb purifications can be significantly increased without the need to change established protocols.
