NCIt definition : A murine IgG2a monoclonal antibody directed against the HLA-Dr10 protein, a cell surface
marker present on over eighty percent of lymphoma cells. When conjugated with a radioactive
isotope, Lym-1 monoclonal antibody selectively transports the cytotoxic radioisotope
to HLA-Dr10-expressing tumor cells, thereby sparing healthy B-cells and normal tissues.
This agent also mediates antibody-dependent cytotoxicity thereby promoting Raji B-lymphoid
cell lysis by human neutrophils. (NCI04);
