Used in reproductive research to measure estrone levels in pig biological samples such as serum, plasma, or urine. Helps monitor ovarian function, track estrous cycles, and assess hormonal imbalances in swine. Commonly applied in veterinary endocrinology, breeding programs, and fertility studies to improve reproductive efficiency in pig farming. The ELISA format allows for high-throughput, sensitive, and specific detection of estrone, making it ideal for research labs focused on animal physiology and hormone dynamics.
