Xanthine/Xanthine Oxidase assay kit

  • For quantitative determination of xanthine
  • Sensitive and accurate
  • Use as little as 10 ┬ÁL samples
  • Simple and convenient: "Add-Incubate-Read" type assay
  • For cell lysate, serum, and other biological samples

Xanthine is a purine base that can be found in most animal tissues and fluids. It is a product in the purine degradation pathway, produced by guanine deaminase from guanine, and by xanthine oxidoreductase from hypoxanthine. Xanthine is degraded to uric acid by xanthine oxidase.

This xanthine assay kit uses a single Working Reagent that combines the xanthine oxidase reaction and color reaction in one step. The change in color intensity of the reaction product at 570 nm or fluorescence intensity at Ex/Em = 530/585 nm is directly proportional to xanthine concentration in the sample.

  • Linear detection range colorimetric assay: 0.01 to 2.5 mM
  • Linear detection range fluorometric assay: 3 to 250 µM
  • 30 minutes room temperature assay
  • Assays using 96-well plates and liquid handling system could allow simultaneous processing tens of thousands of samples per day

Xanthine Oxidase assay kit

The xanthine oxidase assay kit uses a single Working Reagent that combines the xanthine oxidase reaction and color reaction in one step. The change in color intensity of the reaction product at 570 nm or fluorescence intensity at Ex/Em = 530/585 nm is directly proportional to xanthine oxidase activity in the sample.
