STUDIES IN MOLECULAR PATHOLOGY

Abstract
After intravenous injection in mice, rabbit immune complexes, solubilized in antigen excess and containing fluorescent antigens (BSA* or OA*) or fluorescent antibody, or both, were promptly localized in reticuloendothelial cells, and polymorphonuclear leukocytes, of the sinusoids of liver and the red pulp of spleen; in glomeruli and elsewhere in kidney; in capillary endothelium of heart and lung; and in hepatic cells.
