Used in research settings to measure glucose-dependent insulinotropic polypeptide (GIP) levels in mouse samples. This assay helps in studying metabolic disorders such as type 2 diabetes, obesity, and insulin resistance. It enables researchers to evaluate the function of the incretin system, monitor pancreatic beta-cell activity, and assess the impact of therapeutic interventions on gut hormone secretion. Commonly applied in preclinical studies involving animal models of diabetes and metabolic syndrome.
