The hCG-beta Monoclonal Antibody [Clone SPM529] is a mouse IgG1 antibody developed to detect the beta subunit of human chorionic gonadotropin (hCG-β) with high specificity and sensitivity. As the hormone-specific portion of hCG, the beta subunit serves as a critical marker for pregnancy-related tissues and hCG-producing tumors, including choriocarcinoma, invasive mole, and select germ cell neoplasms. Clone SPM529 is optimized for immunohistochemistry (IHC) on formalin-fixed, paraffin-embedded (FFPE) specimens and demonstrates clear cytoplasmic staining in positive tissues.
