Immunogen immunisation with extracted protein of human PSG
Clone BAP3
Isotype IgG1
Specificity BAC2 recognizes exclusively CEACAM7 transiently expressed on the cell surface of transfected BOSC23 cells. BAC2 can be used to distinguish CEACAM7 from all other CEACAM and probably all pregnancy-specific glycoprotein molecules, namely CEACAM1 (B
Purification Protein G
Alternative Name PSG
Background BAP3 reacts with human pregnancy-specific glycoproteins (PSG), a group of closely related secreted glycoproteins which are highly expressed in placental syncytiotrophoblast cells of fetal origin. PSG are commonly expressed in tumors of trophoblast origin (hydatidiform mole, choriocarcinoma). They represent the most abundant fetal protein in the maternal blood at term. The eleven human PSG genes (PSG1-PSG11) form together with the carcinoembryonic antigen (CEA)-related cell adhesion molecule (CEACAM) genes the CEACAM gene family. PSG stimulates secretion of TH2-type cytokines from monocytes. CD9 was shown to represent the monocyte receptor for murine PSG17. PSG are thought to modulate the maternal immune system during pregnancy thus protecting the semiallotypic fetus from rejection.
