Q Sepharose™ XL Ion Exchange Chromatography Media, Cytiva
Protein Purification Protein Purification Resins
Q Sepharose XL is based on a highly cross-linked, bead formed 6% agarose matrix similar to the well established Q Sepharose Fast Flow media.

  • High loading capacities give more productive capture from clarified feedstocks
  • Strong anion exchanger designed for capture steps
  • High chemical stability for effective CIP/sanitization

The hydrophilic nature of the base matrix ensures low levels of non-specific binding leading to low levels of host cell-derived impurities in the elution pool. With its high loading capacities and excellent physical and chemical stability, Q Sepharose XL is suitable for the capture stage of a downstream process, which is characterised by large loads of crude samples. As member of the BioProcess media range, Q Sepharose XL meets industrial demands with security of supply and comprehensive technical and regulatory support.

Dextran chains are covalently coupled to the agarose matrix and modified with quaternary ammonium (Q) strong anion exchange groups through chemically stable ether bonds. The stable agarose matrix and long, flexible chains of dextran with bound charged groups work together to increase loading capacity whilst allowing high flow rates.
