Antihemophilic factor antigen. Localization in endothelial cells by immunofluorescent microscopy. 1973

L W Hoyer, and R P De los Santos, and J R Hoyer

The tissue localization of antihemophilic factor (AHF, Factor VIII) has been determined by immunofluorescent studies using monospecific rabbit antibody to human AHF. Specific staining demonstrating AHF antigens has been identified in endothelial cells of a wide range of human tissues. The staining pattern was observed in endothelial cells of arteries, capillaries, and veins as well as the cells lining hepatic and splenic sinusoids. Specific fluorescence was limited to these endothelial cells in sections of kidney, liver, spleen, lymph node, cardiac and smooth muscle, thyroid, umbilical cord, and skin. Absorption studies established that the staining was specific for cells in which there were proteins that had AHF antigens. The demonstration of fluorescence within the cytoplasm of endothelial cells suggests that these cells synthesize proteins that have AHF antigens.

UI MeSH Term Description Entries
D007106 Immune Sera Serum that contains antibodies. It is obtained from an animal that has been immunized either by ANTIGEN injection or infection with microorganisms containing the antigen. Antisera,Immune Serums,Sera, Immune,Serums, Immune
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008198 Lymph Nodes They are oval or bean shaped bodies (1 - 30 mm in diameter) located along the lymphatic system. Lymph Node,Node, Lymph,Nodes, Lymph
