[Serological identification of an antigen associated with acute lymphoid leukemia]

Using as references a lymphoblastoid cell line established from the pleural effusion of a lymphosarcoma patient and the corresponding autochtonous reactive serum, absorption typing assays resulted in the identification of a cell surface antigen associated with acute lymphoid leukaemia. This antigen, provisionally termed PON, may also be demonstrated on the cells of some acute myelomonocytic leukaemias and lymphosarcomas.
