Development and characterization of monoclonal antibodies to Marek's disease tumor-associated surface antigen

Four monoclonal antibodies, A35, B94, EB29, and G152, against Marek's disease tumor-associated surface antigen have been developed and their specificities studied against a panel of Marek's disease and lymphoid leukosis primary tumors; Marek's disease, and lymphoid leukosis, and reticuloendotheliosis lymphoblastoid cell lines; and normal chicken cells. A35 and G152 are of the immunoglobulin M class, and B94 and EB29 are of the immunoglobulin G1 subclass.
