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.

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.

Secretor Status

The mapping out of the histologic distribution of blood group antigens A and B in human tissues was performed by means of the fluorescent antibody technique. Human hyperimmune sera were conjugated with fluorescein isocyanate and applied to frozen sections of human material obtained at autopsy or after surgical removal. The material examined encompassed A, B, and AB subjects. In the latter the anti-A and the anti-B conjugate elicited the same picture. Group O tissues were used for controls and were uniformly negative. The secretor status of subjects was determined from the saliva or by the Lewis typing of erythrocytes. The results fall into the following main divisions: Endothelia of Vessels.—Widespread localization was demonstrated in the cell walls of endothelium of capillaries, veins, arteries, and of sinusoidal cells of spleen. Stratified Epithelia.—These showed good outlining of cells of the Malpighian (and the granular, when present) layers. In transitional epithelia, cells of the basal and contiguous layers gave specific staining. Mucus-Secreting Apparatus.—Positive staining was obtained in glands, goblet cells, and secreting surface epithelia. In non-secretors there was no identifiable antigen with the important exception of the deeper parts of gastric foveolae, deeper parts of crypts of Lieberkühn of bowel mucosa and Brunner's glands of the duodenum. Various Organs of Secretion and Excretion.—The pancreas (exocrine portion) and the sweat glands were found to produce the antigen irrespectively of secretor status. Breast, prostate, and endometrial glands on the other hand apparently secrete the antigen in conformity with the subject's secretor:non-secretor make-up. Thus the secretor:non-secretor status governs principally the antigens associated with mucous secretions and this in most but not all locations. The possible nature of this control is briefly discussed.

The cellular sites of formation of γglobulin in lymphatic tissues of man and in a representative human lymphoid infiltrate have been studied by fluorescent antibody technique. The findings indicate that γ-globulin is formed in the germinal centers of lymphatic nodules and in the cytoplasm of mature and immature plasma cells of two types—those with and those without Russell bodies. The germinal center cells that synthesize γ-globulin have been designated "intrinsic" cells to distinguish them from the medium and large lymphocytes, and the primitive reticular cells that occur elsewhere and do not produce γ-globulin. Unlike the plasma cells, which function as individual units, the intrinsic cells apparently form γ-globulin only when they are arranged in discrete aggregations. The function, the blood supply, and the systematic cellular arrangement of germinal centers justifies the postulate that they are miniature organs of internal secretion of γ-globulin. The release of γ-globulin from its sites of formation appears to be accomplished by holocrine and apocrine secretion. Presumably, these secretory mechanisms are adaptations required for the production of antibody since they have not been described in parenchymal cells that form the other serum proteins. The cells found to form γ-globulin appear to be identical with those previously shown to form specific antibody in response to a variety of antigens in the experimental animal. This evidence indicates that normal γ-globulin, if it exists, originates in the same cells that produce antibody. It is suggested, also, that each of the 3 morphologically distinct categories of cells that synthesize γ-globulin represents a response to a particular form of antigenic stimulation. Nuclear participation in the process of γ-globulin synthesis was not detected by the technique employed.
