Used in biomedical research to quantify levels of polypeptide YY (PYY) in mouse samples, particularly in studies related to appetite regulation, gastrointestinal function, and energy metabolism. The ELISA kit enables researchers to measure PYY concentration in plasma, serum, or tissue extracts with high sensitivity and specificity. It is widely applied in obesity, diabetes, and neuroendocrinology research to understand how PYY, a gut hormone, influences satiety and feeding behavior in mouse models. The kit supports investigation into gut-brain axis signaling and the development of therapeutics targeting metabolic disorders.
