Chromatography resins are engineered through coordinated design of the matrix, ligand, and coupling chemistry. Their performance reflects a series of trade-offs among capacity, selectivity, mass transfer, pressure, stability, and scalability. Effective resin selection therefore depends on matching the resin’s design intent and performance boundaries to the specific requirements of capture or polishing processes.

As upstream antibody titers continue to rise, downstream purification faces unprecedented productivity challenges. Although continuous chromatography and membrane chromatography offer important advantages, conventional column chromatography remains the cornerstone of industrial antibody purification because of its high binding capacity, excellent reusability, and superior separation performance.
