Anti-CGB1 antibodies are used in the immunodetection of the protein chorionic gonadotropin subunit beta 1. In humans, the canonical protein has a reported length of 187 amino acid residues and a mass of 20.5 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the placenta, testis and pituitary. A member of the Glycoprotein hormones subunit beta protein family, CGB1 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 1, chorionic gonadotropin, beta polypeptide 1, and choriogonadotropin subunit beta variant 1. Western Blot is a widely used application for the CGB1 antibodies listed below. In addition, ELISA is also a common application.
