Used in biomedical research to measure levels of gastrokinin (motilin) in rat samples, this ELISA kit enables the study of gastrointestinal motility regulation. It is applied in preclinical studies investigating digestive disorders, gut hormone secretion, and the effects of pharmaceuticals on gastric activity. Researchers use it to quantify motilin concentration in serum, plasma, or tissue homogenates with high specificity, supporting experiments in endocrinology and gastroenterology. The kit is not intended for diagnostic use but serves as a tool for advancing understanding of gastrointestinal function in rodent models.
