Used in biomedical research to quantitatively measure xanthine oxidase levels in mouse biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly useful in studies related to oxidative stress, inflammation, and metabolic disorders, as xanthine oxidase plays a key role in purine metabolism and reactive oxygen species production. It enables researchers to assess enzyme activity changes under experimental conditions, evaluate drug effects on oxidative pathways, and investigate mechanisms in diseases like gout, cardiovascular disorders, and liver injury in mouse models. The assay provides high sensitivity and specificity, making it suitable for preclinical research and biomarker validation.
