Used in biomedical research to detect and quantify α2-macroglobulin levels in rat biological samples such as plasma, serum, or tissue homogenates. This ELISA kit is particularly useful in studies related to inflammation, immune response modulation, and proteinase inhibition, as α2-macroglobulin plays a key role in trapping proteolytic enzymes and regulating their activity. It is commonly applied in experimental models of liver disease, kidney dysfunction, and neurodegenerative conditions where protease-antiprotease balance is disrupted. The assay enables high-throughput, sensitive, and specific measurement, supporting both basic research and preclinical evaluation of therapeutic interventions.
