General description

Pregnancy-specific β 1-glycoproteins (PSGs), related to the carcinoembryonic antigen family, are major placental polypeptides. Pregnancy specific β-1-glycoprotein 9 (PSG9, PSGII) is found in placenta and sera of pregnant woman and in some cancers. PSG9 may be a useful biomarker for early detection of colorectal cancer.


Synthetic peptide directed towards the N terminal region of human PSG9


Anti-PSG9 polypeptide antibody is used to tag pregnancy specific β-1-glycoprotein 9 for detection and quantitation by Western blotting and in plasma by immunohistochemical (IHC) techniques. It is used as a probe to determine the roles of pregnancy specific β-1-glycoprotein 9 in placenta development and as a possible early biomarker of colorectal cancer.

Physical form

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.
