Used in research settings to quantify levels of xanthine dehydrogenase in biological samples, aiding in the study of purine metabolism, oxidative stress, and related diseases such as gout, ischemia-reperfusion injury, and chronic inflammation. The ELISA kit format allows for sensitive and specific detection of XDH protein in serum, plasma, tissue lysates, and cell culture supernatants. It supports investigations into enzyme regulation, drug effects on metabolic pathways, and biomarker discovery in clinical and preclinical studies.
