Used in reproductive research to measure estradiol levels in pig biological samples such as serum, plasma, or tissue extracts. Helps monitor ovarian function, assess fertility status, and study hormonal changes during the estrous cycle. Widely applied in veterinary endocrinology, animal breeding programs, and experimental studies related to pig reproduction. The kit enables high-throughput, accurate quantification of estradiol, supporting research on reproductive disorders, hormone therapy, and environmental effects on pig fertility.
