Mouse Anti-hCG Beta (Free Specific)
This antibody specifically recognizes the beta subunit of human chorionic gonadotropin (hCG).
Minimal crossreactivity (0.5%) has been observed with the intact hCG molecule and negligible reactivity has been shown with the human luteinizing hormone (LH), follicle stimulating hormone (FSH) and thyroidstimulating hormone (TSH).
Human chorionic gonadotropin exists in 5 different variants (hCG, sulfated hCG, hyperglycosylated hCG, free beta hCG and hyperglycosylated free beta) that share the same amino acid sequence but have different functions (Cole 2012). hCG is a glycoprotein of 237 amino acids. Regular hCG has a molecular weight of 36,000 where oligosaccharides account for 25-30% of the MW (Cole 2010). It is composed of a 92 amino acid alpha subunit, common to the LH, FSH and TSH hormones, and of a unique beta subunit, which is recognized by this antibody.
Production of progesterone is not the only role of hCG: it also has numerous other functions, during pregnancy and as a marker for certain cancers (Cole LA 2012, 2010 and 2009).
