Thermo Scientific™ POROS™ Caprylate Mixed-Mode Cation Exchange Chromatography Resin

Description

POROS Caprylate Mixed-Mode Chromatography Resin is designed to remove moderate to high levels of aggregates during downstream processing of therapeutic antibodies in flow-through mode. As a mixed-mode, weak cation-exchange resin, POROS Caprylate resin effectively removes other impurities, such as host cell proteins and a wide range of high molecular weight species.

Features of POROS Caprylate Mixed-Mode resin include:

• Selective capture of aggregates and hydrophobic high-molecular-weight impurities
• Flow-through design that helps save buffer and material costs
• Excellent scalability and high productivity
• Wide operational range
• Non-animal-derived

POROS Caprylate Mixed-Mode resin operates in flow-through mode which reduces costs, especially when working with more engineered monoclonal antibody derivatives. The unique selectivity of the caprylate ligand contributes to a high yield of the targeted monomer while using established cation exchange resin buffer systems.
