Sephadex ion exchangers are produced by introducing functional groups onto the cross-linked dextran matrix.

• Strong anion exchanger suitable batch techniques
• High binding capacities
• Stable to all commonly used aqueous buffers additives such as 8 M urea and 6 M guanidine hydrochloride
• Avoid using oxidising agents and dextranase

Different types of ion exchangers (DEAE, QAE and CM) and two different porosities (A-25/C-25 and A-50/C-50) are available.

These groups are attached to glucose units in the matrix by stable ether linkages.
