Intracellular localization of λ-carrageenan in the carrageenan granuloma has been demonstrated by a specific fluorescent antibody to the polymer. In general, the fluorescent antibody staining correlated with the intracellular metachromatic staining. The fluorescent antibody technique did not confirm that the extracellular metachromasia was due to λ-carrageenan.

Rabbit antiserum to human myoglobin was used with the indirect fluorescent antibody technique to localize this protein in human skeletal muscle. Specific fluorescence was noted, in rapidly frozen and acetone-fixed sections, to be located at the transverse striations, at the sarcolemmal regions and at certain fibrillar structures within the cell. The antibody fluorescence reaction was shown to be specific for myoglobin, and was not produced by normal rabbit serum of serum of rabbits immunized with bacterial antigens. The reaction was abolished by prior absorption of the antimyoglobin serum with myoglobin, and was found to be absent in tissues deficient in myoglobin (lung, kidney, spleen, liver and uterus). Omission of acetone fixation or delayed freezing resulted in leakage of myoglobin from the cell and loss of specific intracellular localization. Sarcolemmal localization appeared to be somewhat more stable.

HeLa cell cultures infected with adenovirus type 4 were studied by light and phase-contrast microscopy and by the fluorescent antibody technique for visualization of intracellular antigen. The findings were correlated with the growth curve of infectious virus, determined from companion cultures. The results indicated that those cells undergoing characteristic structural changes observable by light microscopy were those which contain viral antigen. The distribution of the majority of the antigen within the infected cells corresponded to that of the regularly aligned granules and crystal-like masses seen in the nuclei of cells in stained and in unfixed cultures. The production of infectious virus was closely correlated with the development of the characteristic nuclear changes.

Antisera against seven strains of Bacteroides fragilis subspecies fragilis were produced from dense suspensions of whole cells. These sera exhibited high agglutination titers with homologous antigens. Reciprocal cross-reactions in agglutination tests with each immunizing strain yielded lower titers. Both the indirect and direct fluorescent-antibody techniques were used to evaluate these reagents in the serological identification of 24 defined strains of B. fragilis subspecies fragilis. Subspecies and even strain specificities were noted with particular antisera. A pooled antiserum and conjugate were prepared and studied. Study results showed that specific and high-titered antisera against strains within this subspecies can be produced by the methods described herein and that possibly more than one serotype exists within the seven strains studied. The development of more antibody pools will be necessary to encompass a wider antigenic coverage before the fluorescent-antibody technique can be relied upon altogether for serologically identifying isolates of B. fragilis subspecies fragilis. Test data showed that the indirect method of fluorescent-antibody staining with whole antiserum is an excellent means of identifying strains of this organism.

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.
