Anti-PSG7 antibodies are used in the immunodetection of the protein pregnancy specific beta-1-glycoprotein 7. In humans, the canonical protein has a reported length of 419 amino acid residues and a mass of 47 kDa. It has been described to be a secreted protein. It is notably expressed in the placenta and testis. A member of the CEA protein family, PSG7 is known to be involved with signal transduction pathways. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include PSBG-7, PSG1, PSGGA, pregnancy-specific glycoprotein 7, putative pregnancy-specific beta-1-glycoprotein 7, and PS-beta-G-7. Immunohistochemistry is the most common application for the PSG7 antibodies listed below. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
