Intensified Antibody Purification Using Membrane Chromatography

This special report presents a study focused on intensified antibody purification through a fully membrane-based chromatography workflow, primarily targeting monoclonal antibody (mAb) production. The report outlines the growing demand for mAb therapies and the need for process intensification (PI) to enhance overall productivity in biomanufacturing. Key methods discussed include rapid-cycling chromatography (RCC) and multicolumn chromatography (MCC), both of which aim to optimize downstream processing in response to heightened upstream yields. The report details the advantages of membrane chromatography over traditional resin-based methods, including improved product yield and reduced costs, making it a viable option for clinical and commercial applications. Experimental data compares the effectiveness of various chromatography techniques, examining parameters such as binding capacity and purification performance. Additionally, the document elaborates on the design of experiments (DoE) approach used to evaluate the purification processes, emphasizing the importance of optimizing conditions for maximum efficiency.
