Surface antigenic markers were detected on three classes of Marek's disease (MD) tumor cells, i.e., MD lymphoma cells, cultured cells of the MSB-1 lymphoblastoid cell line, and JMV lymphoblastic leukemia cells, by indirect membrane immunofluorescent staining with serum from chickens immunized with JMV cells or from rabbits immunized with MSB-1 cells. This surface antigen was not detected on normal chicken lymphocytes, RPL-16 tumor cells (tranedormed by an avian RNA virus, or MD virus-infected fibroblasts that were positive for viral membrane antigen (MA). Furthermore, the surface antigen appeared unrelated to embryonic or histocompatibility antigens. This antigen is provisionally designated as a Marek's disease tumor-associated surface antigen (MATSA). The MATSA's on JMV, MSB-1 and MD lymphoma cells were related but not identical as demonstrated by antiserum titration, absorption and blocking tests with homologous and heterologous systems.
