Used in reproductive biology research to measure kisspeptin levels in biological samples. Helps study the regulation of gonadotropin-releasing hormone (GnRH) secretion, which plays a key role in puberty, fertility, and reproductive function in animals. Commonly applied in veterinary research and endocrinology studies involving goats and other ruminants. Enables investigation of reproductive disorders, seasonal breeding patterns, and hormonal responses to environmental or physiological changes.
