Antigenic Constituents in Pregnancy Plasma which are Undetectable in Normal Non-Pregnant Female or Male Plasma

摘要: Up to four antigenic constituents have been found in the plasma of pregnant women which are not detectable specimens from normal untreated non-pregnant women, or men. They visualized by immunodiffusion methods with hyperimmune rabbit antiserum pregnancy plasma, after exhaustive absorption lyophilized female plasma. These distinct each other as judged their differing electrophoretic mobilites. It is unlikely that they represent any known proteins gel diffusion because used. In addition, it has shown none them human chorionic gonadotropin, placental lactogen, oxytocin, C-reactive protein, oxytocinase (cystine-amino-peptidase), alkaline phosphatase esterase, and unrelated bovine prolactin. Preliminary data revealed one these pregnancy-associated synthesized during course oral hormone contraception.
