title: Evidence for the existence of 2 types of alpha 1-lipoprotein in amniotic fluid from pregnancies older than 20 weeks.
abstract: We have found by means of crossed immunoelectrophoresis that amniotic fluid contains 2 types of alpha 1-lipoprotein after the 20th week of pregnancy. Before that period the alpha 1-lipoprotein profile of amniotic fluid resembles that of serum and migrates as one type only.
