Follicle Stimulating Hormone (FSH) Antigen ≥98%

This lyophilized Follicle Stimulating Hormone (FSH) antigen from Antibodies.com is supplied at ≥98% purity in a 100 µg vial format, intended for immunoassay development and antibody generation workflows. FSH is a heterodimeric glycoprotein gonadotropin secreted by the anterior pituitary, composed of an alpha subunit shared with LH, TSH, and hCG, and a unique beta subunit that confers biological specificity. The beta chain drives receptor binding on ovarian granulosa cells and testicular Sertoli cells, making intact FSH and its isolated subunit valuable targets for research into reproductive endocrinology, fertility diagnostics, and gonadal function. As a high-purity immunogen, this antigen supports the production of polyclonal or monoclonal antibodies against FSH, and it can serve as a reference standard or calibrator in custom assay platforms targeting pituitary gonadotropins. The lyophilized format preserves activity during shipping and allows reconstitution in assay buffer at the working concentration required for coating plates or running standard curves. Storage at -20°C in a dry state is recommended for long-term stability, with aliquots prepared after reconstitution to limit freeze-thaw cycles.
