General description
Formerly E.C. 1.1.3.22
Application
Xanthine Oxidase from bovine milk has been used as a source for superoxide generation. It has also been used as a model enzyme in the internally calibrated electrochemical continuous enzyme assay (ICECEA).
Biochem/physiol Actions
The isoflavanoid genistein was shown to inhibit xanthine oxidase at concentrations between 0.1-4.0 μM and then activate xanthine oxidase at concentrations higher than 5 μM.
Xanthine Oxidase acts as a potential biomarker for oxidative stress. It is also implicated in tissue and vascular injuries such as liver damage, inflammatory diseases and chronic heart failure.
Xanthine oxidase is a molybdenum-containing enzyme that is found in the cytosol, and may be strongly inhibited by flavonoids. It plays a vital role in the metabolism of some drugs, as well as purines and pyrimidines. It is also known to be a biological source of reactive oxygen species.
Physical form
Contains 0.5% sodium salicylate.
Analysis Note
Protein determined by biuret
Other Notes
One unit will convert 1.0 μmole of xanthine to uric acid per min at pH 7.5 at 25 °C. Approx. 50% of the activity is obtained with hypoxanthine as substrate.

Generally, enzyme immobilization on nanoparticles leads to nano-conjugates presenting partially preserved, or even absent, biological properties. Notwithstanding, recent research demonstrated that the coupling to nanomaterials can improve the activity of immobilized enzymes. Herein, xanthine oxidase (XO) was immobilized by self-assembly

Free-radical generation is suspected to play a key role in cardiovascular diseases. Another crucial factor is shear stress. Human umbilical vein endothelial cells (HUVECS), which form the lining of blood vessels, require a physiological shear stress to activate many vasoactive

Cells are exposed to several types of integrin stimuli, which generate responses generally referred to as "integrin signals", but the specific responses to different integrin stimuli are poorly defined. In this study, signals induced by integrin ligation during cell attachment
