title: Identification of the cold-insoluble globulin of plasma in amniotic fluid.
abstract: A fetal and adult plasma protein known as the cold-insoluble globulin (CIg) of plasma has been identified in amniotic fluid. Its concentration relative to the total protein in amniotic fluid is several times higher than that in adult or fetal plasma, suggesting that it arises from amniotic tissues.
