Used in reproductive physiology research to measure gonadotropin-releasing hormone levels in sheep. Enables accurate assessment of hormonal fluctuations related to estrus cycles, ovulation, and fertility. Supports studies in animal breeding, endocrinology, and reproductive health by providing a reliable method to quantify GnRH in biological samples such as serum, plasma, or tissue extracts. Helps monitor the effectiveness of hormone treatments and evaluate neuroendocrine function in experimental models.
