QAE Sephadex A-50

QAE Sephadex A-50 is a strong anion exchanger based on the well documented and well proven Sephadex base matrix.

强阴离子交换剂适合分批技术。
高结合能力。
QAE葡聚糖凝胶A-50离子交换剂是通过在交联的葡聚糖基质上引入官能团来生产的。 这些基团通过稳定的醚键连接到基质中的葡萄糖单元上。

提供不同类型的离子交换剂（DEAE、QAE 和 CM）和两种不同的孔隙率（A-25/C-25 和 A-50/C-50）。

  • Strong anion exchanger suitable batch techniques.
  • High binding capacities.

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.

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