Optimized Purity and Recovery of a Monoclonal Antibody Using Mixed-Mode Chromatography MediaOptimized Purity and Recovery of a Monoclonal Antibody Using Mixed-Mode Chromatography Media

Purity, recovery, and elution volume are important factors and parameters when screening multiple media (resins) for the development of efficient, robust, and economical production processes. Among a selection of mixed-mode media evaluated for the purification of MAb S, CHT™ Ceramic Hydroxyapatite provided the best monomer recovery at 83% in the smallest elution volume with a target purity of 99.5%. Using a bind and elute strategy provided enhanced purification power compared to flow-through modes.
