Used in biochemical and plant physiology research to quantify xanthine dehydrogenase (XDH) enzyme levels in plant samples. This ELISA kit enables researchers to study enzyme activity related to nitrogen metabolism, stress responses, and reactive oxygen species (ROS) production in plants. It is particularly useful in studies involving plant defense mechanisms, senescence, and abiotic stress such as drought or salinity. The assay provides a sensitive and specific measurement of XDH protein concentration, supporting investigations into plant metabolic regulation and signaling pathways. Widely applied in agricultural research and functional genomics to evaluate gene function and environmental impacts on plant health.
