Anti-hCG alpha 4 antibody [INN-hFSH-132] (ab11232)


  • Product nameAnti-hCG alpha 4 antibody [INN-hFSH-132]
  • Description
    Mouse monoclonal [INN-hFSH-132] to hCG alpha 4
  • SpecificityA high affinity antibody recognising the alpha 4 epitope of the alpha-subunit of Human Chorionic Gonadotrophin, hLH, hFSH, hTSH and free alpha-subunit. The recognised epitope comprises amino-acids alpha 15 to alpha 22 of the human sequence. We have data to indicate that this antibody may not cross react with wide range of other species. However, this has not been conclusively tested and expression levels may vary in certain cell lines/tissues.

    • RelevanceHuman chorionic gonadotropin (hCG) is a peptide hormone produced in pregnancy, by the developing placenta and by the fertilized egg after implantation in the uterine wall. Its primary role is in the maintenance of the corpus luteum and causes it to secrete the hormone progesterone. Progesterone enriches the uterus with a thick lining of blood vessels and capillaries so that it can sustain the growing fetus. HCG is composed of two subunits, alpha and beta. The alpha subunit of HCG, however, is identical to the alpha subunit of luteinising hormone, thyroid stimulating hormone and follicle stimulating hormone. Serum human chorionic gonadotrophin testing is accurate 48 hour post conception. Urine human chorionic gonadotrophin testing is a popular method of home pregnancy determination as human chorionic gonadotrophin can be detected in urine
