Used in biomedical research to measure Neuropeptide Y (NPY) levels in rat samples, this ELISA kit enables accurate quantification of NPY concentration in plasma, serum, or tissue homogenates. It is widely applied in neuroscience and endocrinology studies to investigate the role of NPY in appetite regulation, stress responses, anxiety, and metabolic disorders. Researchers use it to evaluate changes in NPY expression under experimental conditions such as diet manipulation, drug treatment, or disease models like obesity and depression. The assay supports high-throughput analysis with high sensitivity and specificity, making it a reliable tool for preclinical studies involving the central and peripheral nervous systems.
