Used in biomedical research to quantify levels of β-melanocyte stimulating hormone (β-MSH) in biological samples such as serum, plasma, or cell culture supernatants. Enables researchers to study the role of β-MSH in appetite regulation, energy homeostasis, and pigmentation. Commonly applied in endocrinology and neuroscience studies, particularly in models of obesity, metabolic disorders, and hypothalamic function. Provides a sensitive and specific means to monitor changes in β-MSH concentration in response to physiological or pharmacological interventions.
