The indirect fluorescent antibody technique was used to determine the cellular site of human chorionic gonadotropin (H.C.G.) in normal and toxaemic placentas, and in choriocarcinomas. In placental tissue specific fluorescence was located in the syncytial cells of the chorionic villi but not in the cytotrophoblast cells. In choriocarcinomas specific fluorescence was seen in the syncytial giant cells. No distinct difference could be demonstrated between normal and "toxic" placentas. Differences in the content of H.C.G. in placentas at various stages of pregnancy were noted. Maximum amounts were demonstrated in tissue of less than 14 weeks gestation. Lesser quantities could be seen in more mature placentas and some specific fluorescence could be seen in most full term placentas.

Rapid Quantification

Fluorescent antibody technique by the monoclonal antibody method is very useful and helpful for the rapid quantification and in situ detection of the specific bacteria like nitrifiers in a mixed baxterial habitat such as a biofilm. In this study, twelve monoclonal antibodies against Nitrosomonas europaea (IFO14298) and sixteen against Nitrobacter winogradskyi (IFO14297) were raised from splenocytes of mice (BALB/c). It was found that these antibodies exhibited little cross reactivity against various kinds of heterotrophic bacteria. The direct cell count method using monoclonal antibodies could exactly detect and rapidly quantify N. europaea and N. winogradskyi. Moreover, the distribution of N. europaea and N. winogradskyi in a biofilm could be examined by in situ fluorescent antibody technique. It was shown that most of N. winogradskyi existed near the surface part and most of N. europaea existed at the inner part of the polyethylene glycol (PEG) gel pellet, which had entrapped activated sludge and used in a landfill leachate treatment reactor. It was suggested that this monoclonal antibody method was utilized for estimating and controlling the population of nitrifying bacteria as a quick and favorable tool.

Fluorescent labeled antibodies were used for the demonstration of uromucoid. This urine specific mucoprotein is demonstrably present only in the epithelial cells of the proximal segments of the normal human renal tubules and in the matrix of human kidney stones of all the common crystalline compositions.
