With a high binding capacity and small bead size, Capto™ SP ImpRes strong cation exchanger is a good choice for reliable and robust polishing steps in industrial purification. High-resolution intermediate purification and polishing resin based on the well-established Capto™ platform with traditional ligands. Smaller particle size compared with Capto™ S. Flexible process design due to large operational window of flow rates and bed heights. High throughput purifications easy to optimize and scale-up. Higher manufacturing productivity enables improved process economy. Resin fulfills industrial demands for security of supply, robust performance, and regulatory support Designed for large feed volumes Capto™ SP ImpRes is a strong cation exchanger for the high-throughput intermediate purification and polishing steps of a wide range of biomolecules. This chromatography resin is part of an expanded high-resolution platform based on the high-flow agarose Capto™ product line. By combining the high-flow characteristics of Capto™ resin with a small particle size, Capto™ SP ImpRes delivers excellent pressure-flow properties with impressive resolution. The ability to run at higher flow rates and higher bed heights also increases flexibility in process design. Suits large-scale purification processes Capto™ SP ImpRes is a BioProcess™ chromatography resin developed for large-scale purification of biopharmaceutical proteins. Based on the well-established Capto™ base matrix and with traditional ionic group ligands, it provides many opportunities for improved productivity and straightforward process development.
