Anti-Human Chorionic Gonadotropin β (HCGβ) Antibody

This mouse monoclonal IgG1 reagent from Antibodies.com targets the β subunit of human chorionic gonadotropin (β-hCG), the glycoprotein hormone central to pregnancy testing and to monitoring trophoblastic and germ cell tumors. Because luteinizing hormone, follicle-stimulating hormone, and thyroid-stimulating hormone share the α subunit with hCG, β-subunit specificity is what lets an immunoassay distinguish genuine hCG elevation from cross-reactivity caused by related pituitary gonadotropins.

The antibody is supplied as 1 mg of DEAE-purified protein in unconjugated form in a single-use vial, ready for direct labeling or for use as a capture or detection reagent in ELISA. Reproductive endocrinology labs, prenatal screening programs, and oncology groups tracking testicular germ cell and gestational trophoblastic disease combine this β-specific clone with an α-specific partner to selectively measure intact hCG and free β-hCG forms in maternal and oncologic samples.

The product is intended for research use only.
