About this item

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.

Suitable for batch techniques
High binding capacities
Well-proven and widely used especially in approved plasma fractionation processes (DEAE Sephadex™ A-50 only)

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.
