| pregnancy-associated beta-plasma protein | A beta-globulin now believed to be a pregnancy-specific protein. Its plasma levels increase steadily during pregnancy until the end of gestation. (12 Dec 1998) |
| pregnancy-specific beta 1-glycoprotein | A glycoprotein with the electrophoretic mobility of a beta-1 globulin. It is produced by the placental trophoblast and secreted into the maternal bloodstream during pregnancy.
