A comparative immunoelectrophoretic study of the proteins of the placenta and of the fetal blood serum

By employing Levy-Polonovski and Wadsworth-Hanson immunoelectrophoretic methods with short trough, and also the Vasileisky method of stereoimmunological development it was shown that electrophoregrams of placental homogenate and umbilical cord blood serum possess identical components: 1) one in albumin fraction, 2) one in {ie162-1} fraction, 3) one in {ie162-2} fraction, and 4) one in γ-globulin fraction; cross-reacting components (one in {ie162-3} fraction and two in γ-globulin fraction), as well as related but not identical components in albumin fraction (spore). The placenta used in the experiments was duly washed of blood, so that, following immunoelectrophoretic tests by Grabar-Williams and antiserum development as against adult human serum in optimal concentration the arcs were barely perceptible. However, the same antiserum, applied to a human serum electrophoregram, gave eight quite distinct bands.
