General description

The Sephadex® ion exchangers contain a cross-linked dextran matrix with functional groups. These groups are linked by stable ether linkages to the glucose units in the matrix. DEAE Sephadex can be used in ion exchange chromatography for purifying and isolating proteins.

A25120-100G′s updated product number is GE17-0170-01
A25120-500G′s updated product number is GE17-0180-02

Application

DEAE-Sephadex® A-25 has been used:
  • to form DEAE-Sephadex A-25 (formate form) for glucosinolates (GLS) extraction using horseradish plants
  • in the estimation of GLS content in Chinese kale sprouts
  • production and purification of endozepine from astrocytes
  • to identify and label an insulin-activated nitric oxide synthase inhibitor (protein) in acute myocardial infarction (AMI) patients

Features and Benefits

  • Weak anion exchanger
  • Suitable for batch techniques
  • High binding capacities
  • Non-reactive to commonly used aqueous buffers additives such as 8 M urea and 6 M guanidine hydrochloride
