Anti-CGB2 antibodies are used in the immunodetection of the protein chorionic gonadotropin subunit beta 2. In humans, the canonical protein has a reported length of 163 amino acid residues and a mass of 17.4 kDa. It has been described to be a secreted protein. It is reported to be expressed in the placenta, testis and pituitary. A member of the Glycoprotein hormones subunit beta protein family, CGB2 is known to be involved with GPCR signaling pathways. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include chorionic gonadotropin beta subunit 2, chorionic gonadotropin, beta polypeptide 2, product of CGB2, and choriogonadotropin subunit beta variant 2. Some CGB2 antibodies may have been used in research and have associated citations. ELISA, Western Blot, and Immunofluorescence are common applications for these antibodies.
