Used in biomedical research to quantify Neuropeptide Y (NPY) levels in biological samples such as plasma, serum, and tissue homogenates. Enables investigation of NPY's role in appetite regulation, stress responses, and metabolic disorders. Widely applied in neuroscience, endocrinology, and obesity-related studies to assess NPY concentration changes under experimental or clinical conditions. Provides a sensitive and specific tool for high-throughput analysis in research settings. Not intended for diagnostic use.
