Anti-PSG11 antibodies are used in the immunodetection of the protein pregnancy specific beta-1-glycoprotein 11. In humans, the canonical protein has a reported length of 335 amino acid residues and a mass of 37.1 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the placenta and testis. It is a member of the CEA protein family. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include PSBG-13, PSG13, PSG14, PS-beta-G-11, PS-beta-G-13, pregnancy-specific beta-1-glycoprotein 13, and PSBG-11. Some PSG11 antibodies may have been used in research and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
