Immunoelectrophoretic studies of hydatidiform mole fluid

Antiserum to fluid in hydatidiform mole cysts was produced. Immunoelectrophoretic studies showed that, even after absorbing out HCG from molar fluid, a couple of precipitin arcs still appeared when such molar fluid was reacted with anti-molar fluid serum. Column chromatography with Sephadex G-100 revealed that the antigens other than HCG were eluted in the same fraction as HCG
