Oxytocinase-immunohistochemical demonstration in the immature and term human placenta.

Oxytocinase (cystine aminopeptidase) was purified from human retroplacental serum by a combination of fractional precipitation, hydroxylapatite chromatography and gel exlusion chromatography on Sephadex G-200. The purified enzyme possessed a specific activity of 980 mIU/mg using L-cystine-di-p-nitroanilide as substrate. This represented a 3200 fold concentration from the starting material in an overall yield of 12%. Antibodies against oxytocinase were raised in rabbits and the gamma-globulins fraction labelled with fluorescein isothiocyanate prior to its use in the immunofluorescence histochemical localization of the enzyme in human placental tissue. Oxytocinase was confined to the syncytiotrophoblastic cells of normal term, and immature placentas as well as in placentas from patients suffering from severe toxaemia. Specific immunofluorescence was also present in the outer margins of the chorion and to a lesser extent in the amnion.[1]
