SP Sepharose^™ XL

SP Sepharose^™ XL is a strong cation exchanger designed for use in the capture steps of biomolecules from clarified feed-stocks.

SP Sepharose^™ XL is based on a highly cross-linked, bead formed 6% Agarose matrix similar to the well established SP Sepharose^™ Fast FLow media. Dextran chains are covalently coupled to the Agarose matrix and modified with sulphopropyl (SP) strong cation 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


With its high loading capacities and excellent physical and chemical stability, SP 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, SP Sepharose^™ XL meets industrial demands with security of supply and comprehensive technical and regulatory support.
