Introduction Process intensification is an approach to improve operational throughput by running a manufacturing process or unit operation differently. In mAb purification, intensified processing can remove bottlenecks created by high bioreactor titers, increase manufacturing flexibility for multi-product facilities, and reduce cost of goods while increasing the focus on product quality. This work focuses on intensifying the anion exchange (AEX) mAb polishing step. AEX polishing is commonly used to provide clearance of host cell protein (HCP) and virus impurities.
