Specific reactivity of human monoclonal antibody AE6F4 against cancer cells in tissues and sputa from lung cancer patients.
In vitro immunization of normal human peripheral lymphocytes by the co-cultivation with A549 cells (a human lung adenocarcinoma cell line), followed by the hybridization with the partner cell line A4H12, resulted in the efficient generation of hybridomas which produce human monoclonal antibodies of IgG or IgM isotype. Immunohistochemical and immunocytological studies showed that one of those monoclonal antibodies, termed AE6F4, was specifically reactive to lung cancer tissues as well as cancer cells in sputa.
