Used in biomedical research to measure growth hormone-releasing factor (GH-RF) levels in biological samples such as serum, plasma, or cell culture supernatants. The kit enables researchers to study the regulation of growth hormone secretion, assess pituitary function, and investigate endocrine disorders. It is commonly applied in studies related to growth abnormalities, metabolic diseases, and neuroendocrine signaling. The assay provides a sensitive and specific method for quantifying GH-RF concentrations, supporting both clinical research and drug development.
