Used for the quantitative measurement of xanthine oxidase (XOD) activity in rabbit biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to assess XOD levels in studies related to oxidative stress, inflammation, and metabolic disorders. It is commonly applied in preclinical research involving rabbit models of cardiovascular disease, liver dysfunction, and gout. The assay provides a sensitive and specific method to monitor changes in XOD activity in response to experimental treatments or disease progression.
