Pregnancy specific beta glycoprotein is produced by the syncytiotrophoblast and secreted into the maternal peripheral circulation reaching levels of approximately 200 m/liter in normal pregnancy at term. In the present study the distribution of this newly defined placental protein was examined in maternal and fetal compartments in 12 patients at delivery.
