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

Glucose, enzymatically released from pulp fiber sludge, was combined with inorganic salts and used as a growth medium for Alcaligenes eutrophus, a gram-negative strain producing poly(3-hydroxybutyrate) (PHB). By controlling the concentrations of the inorganic salts in the growth medium, almost

In this work, a characterization of reagent chromophore 5-(4-sulphophenylazo)-8-aminoquinoline [SPA] by IR and 1H RMN was carried out and a pK(a) value of 3.55+/-0.03 was found as well. An 1:2 stoichiometry for the Cu(II)-SPA complex was determined at pH 9

Abl family kinases have been implicated in the regulation of cell morphogenesis and migration, but the molecular mechanisms through which they operate are not fully elucidated. We applied the bump-hole technique, pioneered by Shokat and colleagues, to identify direct substrates

A requisite step in the biosynthesis of tRNA is the removal of 5' leader sequences from tRNA precursors. We have detected an RNase P activity in yeast mitochondrial extracts that can carry out this reaction on a homologous precursor tRNA.
