Fluorescent Antibody Staining

The intralobular distribution of nicotinamide adenine dinucleotide phosphate (NADPH)-cytochrome c (P-450) reductase (NADPH:ferricytochrome oxidoreductase, EC 1.6.2.4) in rat liver has been investigated by means of two quantitative immunohistochemical techniques: microdensitometric quantitation of unlabeled antibody peroxidase-antiperoxidase staining and microfluorometric analysis of indirect fluorescent antibody staining. Utilizing sheep antiserum elicited against NADPH-cytochrome c (P-450) reductase that had been isolated and purified to apparent homogeneity from rat liver microsomes, the reductase was detected within hepatocytes throughout the liver. However, differences in the intensity of staining of hepatocytes within different regions of the liver lobule were readily apparent after completion of both immunohistochemical staining procedures. These visual findings were verified by microdensitometric and microfluorometric analyses of immunohistochemical staining, both of which revealed that approximately the same degree of staining for NADPH-cytochrome c (P-450) reductase was produced within the centrilobular and midzonal regions of the liver lobule, whereas periportal hepatocytes were stained with significantly less intensity. These results demonstrate that the application of either microdensitometry in conjunction with unlabeled antibody peroxidase-antiperoxidase staining or microfluorometry after indirect fluorescent antibody staining can be used to quantitatively determine the intratissue distributions of antigens.

Fluorescent Antibody Staining

The pathogenesis of Mycoplasma pneumoniae infection was studied in the Syrian hamster with qualitative and quantitative culture methods and special histopathologic techniques. The animals were readily infected with the mycoplasma, which multiplied throughout the respiratory tract. Sensitivity of this experimental host to infection was indicated by the 50 per cent infective dose, which was 10 colony-forming units of the organism. Inoculation consistently resulted in the production of peribronchial pneumonitis which was induced by the mycoplasma. The organisms were visualized in a superficial location in the mucosa of involved bronchi, by means of indirect fluorescent antibody staining and by a modification of the Brown and Brenn technique. The data indicate applicability of the hamster to the study of problems concerned with M. pneumoniae disease which are impractical or impossible to resolve in the human host.

Fluorescent Antibody Staining

A fluorescent staining procedure for Trichinella spiralis and the appearance of the stained larvae are described. The applicability of the method to the sero-diagnosis of trichinosis was investigated. The results obtained both with the experimental and human sera agreed well with the complement-fixation results. In titrating 9 experimental sera and 36 sera from parasitologically proved or clinically diagnosed cases of trichinosis in humans, higher titers were obtained by the immunofluorescent staining, indicating that this test is somewhat more sensitive.
