Summary
Specific immunofluorescence of human thymic epithelial cytoplasm was obtained with antibodies to supernatant of thymic epithelial cultures, and with anti-prealbumin antibodies. These antibodies also reacted with normal serum but not with serum from Di George patients. The data indicates that thymic epithelium and a component of the prealbumin fraction of normal serum share a common antigen believed to be thymic hormone.
