NCIt definition : A low-fucose, human-mouse chimeric IgG1 monoclonal antibody with potential antineoplastic
activity targeting at the ganglioside GD3, a surface antigen expressed on many malignant
melanoma cells. Monoclonal antibody KW-2871 binds to GD3-positive cells, thereby initiating
antibody-dependent cytotoxicity against GD3-positive cells. This agent is prepared
by fusing murine immunoglobulin (Ig) light and heavy variable regions derived from
the murine IgG3 antibody KM-641 to a human constant (Fc) region. The low fucose content
of the oligosaccharide side chains of this antibody may enhance binding of the antibody
Fc region to lymphocyte Fc receptors.;
