Purification and Downstream Processing Services

Cell Culture Company offers a comprehensive suite of purification and downstream processing services transforming your biomolecules into purified ready-to-use products. We leverage extensive expertise, various technologies, and custom configurations to seamlessly bridge the gap between research and development to large-scale commercialization.

Trusted Purification for Diverse Biomolecules:

  • Protein Types: Purify monoclonal antibodies (IgG, IgM), antibody fragments (Fab, F(ab)2, scFv, BiTE, sdAb, Bispecific), recombinant proteins (Fc-Fusion, His-tagged, FLAG-tagged, GST-tagged, MBP-tagged, etc.), and more.
  • Chromatography: Employ your preferred protocol including affinity chromatography (Protein A/G/L, CaptureSelect, IMAC, Glutathione), mixed-mode chromatography (Capto™ adhere/MMC, CHT), ion exchange, hydrophobic interaction, and size exclusion tailored to your specific biomolecule and desired purity.
  • Technical Services: Leverage our expert team for technology transfer, process development, non-GMP (RUO/Pre-Clinical) manufacturing, process evaluation and validation, and GMP manufacturing support.
  • Scale: Process development and purification from analytical to preparative scale, handling microgram to multi-gram quantities.

Streamlined Processing:

  • Clarification: Remove cell debris and large impurities using centrifugation, microfiltration, or other techniques.
  • Polishing: Achieve high-purity final product through advanced chromatography or other polishing steps.
  • Viral Inactivation and Filtration: Ensure product safety and regulatory compliance with dedicated viral inactivation and filtration processes through our vendors.
  • Ultrafiltration/Diafiltration: Concentrate and exchange buffers for downstream applications.
  • Sterile Filtration: Guarantee product sterility for final formulation and administration.
  • Formulation: Develop and optimize formulations for stability, long-term storage, and desired delivery route.
