Capto adhere ImpRes resin

• Cat#No#: Ca-469C
• Product Overview: This multimodal, strong anion exchange resin supports effective mAb polishing in the second or third step of a purification scheme downstream of the protein A capture step.
• Description: Capto adhere ImpRes is a BioProcess chromatography medium (resin) for high-resolution polishing of monoclonal antibodies (MAbs) and other biomolecules. The strong anion exchange multimodal ligand displays high selectivity compared with traditional ion exchangers, which allows the possibility to solve challenging purification problems. Main contaminants in MAb processes such as DNA, host cell proteins (HCP), leached protein A, aggregates, and viruses are efficiently separated. Capto adhere ImpRes is an excellent choice for purification of MAb with high aggregate content. The efficient virus removal provided by the chromatography medium also allows two-step purification of MAbs with Capto adhere ImpRes as the final polishing step. Polishing can be performed in either bind and elute (binding) or flowthrough (nonbinding) modes.
• Characteristic: High yields achieved through the high-resolution beads and selectivity of the ligand.
  Efficient removal of aggregates, viruses, and main contaminants in mAb processes.
  Enables use of a platform approach to mAb process development.
  Allows separation of mAb charged variants.
  Resin fulfills industrial demands for security of supply, robust performance, and regulatory support

• Cleaning-in-place: Precipitated hydrophobically bound proteins or lipoproteins: Wash with at least 3 column volumes of 1 M NaOH at a low flow velocity with reversed flow direction. Contact time at least 15 min.
  Ionically bound proteins: Wash with 0.5 to 2 column volumes of 2 M NaCl with reversed flow direction.
  Lipids and very hydrophobic proteins: Wash with 1-propanol 1 to 5% or isopropanol 5 to 30%. 1-propanol has a higher flash point and might be preferred in an industrial environment.

• Sanitization: To reduce microbial contamination in the packed column, sanitization using 0.5 to 1 M NaOH with a contact time of 1 hour is recommended.
