Purification
Antibody purification is a cornerstone of biopharmaceutical manufacturing. It not only determines the quality of the final product but also has a significant impact on the overall economics and competitiveness of production processes, which are increasingly challenged by cost pressures and rising regulatory requirements. At the same time, sustainability has become a critical factor: manufacturers are expected to reduce resource consumption without compromising safety, yield, or purity.
This is exactly where YMC’s latest Whitepaper comes in. It explores the role of ion exchange chromatography (IEX) in antibody purification and demonstrates how efficiency and sustainability can be brought together in practice. Central to this discussion is the question of how to select the most suitable resin in order to make purification processes more robust, productive, and environmentally responsible.
The Whitepaper explains in detail which parameters drive resin performance – from dynamic binding capacity and selectivity to pressure-flow behaviour and chemical stability. It becomes clear that resins not only impact product purity but also dictate long-term process efficiency and environmental footprint. For instance, resins with high binding capacity can reduce the number of purification cycles required, lowering buffer and water usage. Likewise, chemically stable materials enable multiple CIP cycles, extending resin lifetime and reducing waste.
The included case studies make this tangible. One optimised three-step monoclonal antibody purification process shows how the use of BioPro IEX Q75 and S75 resins lead to significantly higher yields and efficient removal of impurities such as HCPs and DNA, achieving purity levels of over 98% while saving both time and costs. Another study highlights how BioPro IEX SmartSep resins maintain high binding capacities across a range of pH levels, salt concentrations, and flow rates, offering flexibility and reliability even under varying process conditions.
Beyond batch process improvements, the Whitepaper explores continuous chromatography as a promising approach for the future of antibody purification. YMC’s twin-column systems, combined with dynamic process control, enable higher throughput, eliminate re-chromatography steps, and reduce QC efforts, all while lowering the environmental footprint. This approach exemplifies the shift towards more agile, resource-efficient, and sustainable biomanufacturing.
Antibody purification today must deliver more than impurity removal. It is a key lever for ensuring product quality, economic viability, and sustainability. With the right combination of advanced resins, stable CIP cycles, optimised flow conditions, and innovative continuous technologies, manufacturers can achieve greater efficiency, lower costs, and reduced environmental impact - making their processes fit for the future.
