Used in biomedical research to measure ghrelin levels in mouse tissue samples, particularly in studies related to appetite regulation, metabolism, and gastrointestinal function. The kit enables researchers to quantify both acylated and des-acylated forms of ghrelin in brain and intestinal tissues, supporting investigations into energy balance, obesity, diabetes, and neuroendocrine signaling. It is a valuable tool in preclinical studies involving mouse models of metabolic disorders.
