Used in agricultural and veterinary research to measure levels of Growth Differentiation Factor 9 (GDF-9) in pig samples, this ELISA kit helps in studying ovarian function and follicular development in sows. It supports research on reproductive efficiency, fertility evaluation, and breeding optimization in swine production. The kit enables accurate quantification of GDF-9, a protein involved in regulating early follicle growth, making it valuable for reproductive physiology studies and developing strategies to improve litter size and overall reproductive performance in pigs.
