DEAE Sephadex™ A-25 and DEAE Sephadex™ A-50 are weak anion exchangers. Sephadex™ ion exchangers are produced by introducing functional groups onto the cross-linked dextran matrix. These groups are attached to glucose units in the matrix by stable ether linkages.

• Weak anion exchanger suitable for batch techniques
• High binding capacities
• Well-proven and widely used
• Stable to all commonly used aqueous buffers additives such as 8 M urea and 6 M guanidine hydrochloride

These groups are attached to glucose units in the matrix by stable ether linkages. Different types of ion exchangers (DEAE, QAE and CM) and two different porosities (A-25/C-25 and A-50/C-50) are available.
