Human HCG beta (Active)

The HCG beta subunit is the hormone-specific chain of human chorionic gonadotropin, a glycoprotein produced by syncytiotrophoblast cells during gestation and by certain trophoblastic and germ cell tumors. Unlike the shared alpha subunit common to LH, FSH, and TSH, the beta chain confers immunological and biological specificity, making this active protein a key reagent for pregnancy research, oncology biomarker studies, and reproductive endocrinology investigations.

Supplied by Antibodies.com as a 500 µg liquid preparation, the unconjugated protein functions as an immunogen, assay calibrator, or positive control in antibody development, western blot validation, and receptor binding studies. Researchers use HCG beta to raise anti-beta subunit antibodies, evaluate cross-reactivity in heterophilic antibody assays, and characterize signaling through the LH/CG receptor in cell-based systems.

For stability, aliquot the protein upon receipt and store at -20 °C or lower; avoid repeated freeze-thaw cycles to preserve bioactivity. The reagent is intended for research use only and is not approved for diagnostic or therapeutic applications.
