ELECTRON MICROSCOPIC OBSERVATIONS ON ANTIBODY-PRODUCING CELLS IN LYMPH AND BLOOD

Abstract
Antibody-producing cells have been identified among cells obtained from efferent lymphatic vessels, the thoracic duct, and peripheral blood. These cells, which produced plaques of hemolysis and which were quite rare (20 to 50 per million), due in most instances to 19S antibody, were located and studied by electron microscopy.
