Description

β-Hcg CAS NO 56832-34-9 is a highly purified glycoprotein hormone, specifically the beta subunit of human chorionic gonadotropin. This compound is of critical importance for its role in diagnostic assays and biopharmaceutical research, serving as a key reference standard. It is essential for manufacturers and research institutions in the in-vitro diagnostics (IVD), pharmaceutical development, and clinical research sectors who require precise and reliable biological materials.

Application

• Immunoassay Calibration: Primary use as a reference standard for calibrating and validating pregnancy and fertility diagnostic tests (ELISA, CLIA, RIA).
• Antibody Production: Used as an immunogen for generating highly specific monoclonal and polyclonal antibodies against hCG.
• Biopharmaceutical Research: Critical component in studies of hormone function, receptor binding, and reproductive biology.
• Quality Control Reagent: Serves as a positive control material in the quality assurance processes of diagnostic kit manufacturing.
• Academic & Clinical Studies: Utilized in research investigating trophoblastic diseases, certain cancers, and endocrinology.
