Used in research settings to quantify levels of follicle-stimulating hormone inhibiting protein (follicstatin) in biological samples such as serum, plasma, or cell culture supernatants. The kit enables accurate measurement of follicstatin concentration through enzyme-linked immunosorbent assay (ELISA), supporting studies in reproductive physiology, ovarian function, and pituitary hormone regulation. Commonly applied in veterinary research, animal breeding studies, and endocrinology to understand folliculogenesis and reproductive health in bovine models. Also useful in monitoring hormonal imbalances and evaluating the effects of treatments on reproductive systems in experimental animals.
