Immunogen:Native Full Length Protein corresponding to Human CGB3.P0DN86,
Specificity:The antibody recognizes the whole hCG beta and the C-terminal end part of hCG beta, as well as the hCG dimer molecule. It does not react with hCG alpha, FSH, LH, TSH and albumins (evaluated by simple-binding ELISA using 1.00 µg/well purified antigens (WHO standards) and 1.00 µg/ml primary antibody concentrations). This antibody labels the cytoplasm of hCG beta producing (trophoblastic) cells in placenta, mola hydatidosa, choriocarcinoma, embryonal carcinoma and some undifferenciated lung cancers, as well as, the JAR choriocarcinoma cell line. It does not react with cells of normal endometrial, testicular tissues and lung (tested by immunohistochemistry on formalin-fixed, paraffin-embedded tissue sections using the Streptavidin-biotinylated peroxidase method).

HCG beta also known as beta hCG or hCGΒ is a subunit of the human chorionic gonadotropin (hCG) protein. This protein plays critical roles in human reproduction. hCG is a glycoprotein hormone composed of alpha and beta subunits with the beta subunit being unique to hCG and conferring its biological specificity. The mass of the beta hCG is approximately 22.2 kDa. hCG beta is expressed mainly in placental trophoblastic cells during pregnancy where it stimulates the corpus luteum to produce progesterone. This progesterone production is essential to maintain the uterine lining for embryo implantation and growth.
Biological function summary
HCG beta plays a significant role in gestational development. It is not a standalone protein but part of the larger hCG complex conferring specific hormonal activity when paired with the common alpha subunit. This activity involves supporting fetal-placental development and enabling maternal immune tolerance to the embryo. As a marker hCG beta levels are measured in pregnancy tests to confirm conception. In addition to pregnancy-related functions hCG beta has been detected in certain cancers making it useful as a tumor marker. It sometimes gets used in clinical settings to monitor trophoblastic disease and germ cell tumors.
Pathways
HCG beta is intricately involved in reproductive signaling pathways. It plays an important role in the cAMP-PKA pathway by acting through the luteinizing hormone/choriogonadotropin receptor which regulates steroidogenesis in the reproductive system. hCG beta’s activity leads to the stimulation of downstream proteins such as progesterone which modulates various reproductive and systemic effects. The involvement of hCG beta in the Wnt signaling pathway has also been suggested indicating its broader role in cellular growth and differentiation making it an influential factor in both pregnancy and certain oncogenic processes.
HCG beta holds significant importance in oncology and reproductive health. Elevated levels of hCG beta are associated with gestational trophoblastic diseases such as choriocarcinoma a fast-growing cancer originating in the uterus. The protein’s abnormal presence is often an indicator in testicular cancer specifically germ cell tumors where it serves as a marker for diagnosis and treatment monitoring. These connections make hCG beta a valuable target for understanding tumor biology and developing diagnostic strategies. Further interactions with related proteins such as the luteinizing hormone receptor highlight its function in these pathogenic conditions.
