Capto SP ImpRes resin

• Cat#No#: Ca-447C
• Product Overview: 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.
• Description: Capto SP ImpRes is strong cation and strong anion exchangers for the high-throughput intermediate purification and polishing steps of a wide range of biomolecules. Both chromatography media (resins) are part of platform of high-resolution media based on the Capto product line.
  By combining the high-flow characteristics of Capto media with a small particle size, Capto SP ImpRes deliver excellent pressure-flow properties with excellent resolution. The ability to run at higher flow rates and higher bed heights increases productivity and flexibility in process design.
• Characteristic: 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.
