Q Sepharose XL, 10 L, Cytiva (CAT#: STEM-C-1571-LC)

Q Sepharose XL manufactured by Cytiva is a strong anion exchanger with high loading capacities and excellent physical and chemical stability, ideal for capture steps of biomolecules from clarified feed-stocks. Q Sepharose XL is based on a highly cross-linked, bead formed 6% agarose matrix similar to the well established Q Sepharose Fast Flow resin. 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.

High loading capacities give more productive capture from clarified feedstocks
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
