Answer:Capto SP ImpRes is a strong cation exchanger that separates proteins by their interaction with negatively charged ligands under suitable buffer conditions.
Answer:Its small bead size and high-flow agarose matrix support high-resolution separation during intermediate purification and polishing.
Answer:The product is a 10 L bulk-resin pack for filling compatible chromatography columns; it is not a prepacked column.
Capto™ SP ImpRes is a strong cation exchange chromatography resin designed for high-resolution intermediate purification and polishing of proteins. The Capto platform combines a rigid, high-flow agarose matrix with smaller beads than standard Capto S, supporting sharp separations and efficient mass transfer. The 10 L bulk-resin presentation is intended for packing process-scale columns, including workflows targeting separation of product-related charge variants and residual impurities. Protein loading depends on feed pH, conductivity and the target molecule’s charge; equilibration and elution conditions must therefore be selected for the intended protein. The resin can support elevated flow rates and a broad range of bed heights during process development and scale-up. Column packing quality, pressure-flow behavior and chromatographic resolution should be established at the selected operating scale before transferring the process.
