NCIt definition : A murine IgG2a monoclonal antibody with potential antineoplastic activity. Monoclonal
antibody L6 binds to the L6 antigen, a cell surface glycoprotein overexpressed in
many carcinomas, and induces antibody-dependent cell-mediated cytotoxicity and complement-dependent
cytotoxicity against L6-expressing tumor cells. This agent may be conjugated with
various toxins in order to target their cytotoxic activity to tumor cells expressing
the L6 antigen. (NCI04);
