Xanthine oxidase (XO) is a key enzyme broadly distributed in mammalian tissues, playing a central role in purine metabolism. In humans and other species, XO catalyzes the oxidative hydroxylation of hypoxanthine, producing: uric acid, superoxide radicals and hydrogen peroxide. As a major source of reactive oxygen species (ROS), XO is closely linked to the development of various oxidative stress-related diseases.

BQC Xanthine Oxidase Activity Assay Kit offers a simple, one-step protocol for measuring XO activity in a wide variety of samples with high reproducibility and speed.
