Location of Feline Leukemia-Sarcoma Group-Specific Antigen in Infected Human Tissue Culture Cells

摘要

Feline leukemia-sarcoma group-specific antigens were located in human embryo cells infected with feline leukemia and feline sarcoma viruses. This was done by using the fluorescent-antibody and enzyme-labeled antibody techniques at both light and electron microscopic levels. The antigens were found to be exclusively intracytoplasmic, diffuse, and located in discrete punctate foci.
