Human anomalous killer (AK) cells lyse freshly isolated human melanoma cells which are insensitive to human natural killer cell-mediated lysis. Monoclonal antibody Leo Mel 3, an IgM (k), produced by a hybridoma obtained from a mouse immunized with human melanoma cells, binds to melanoma cells and inhibits their conjugate formation with AK cells as well as their AK cell-mediated lysis. Other IgM antibodies from the same fusion that bind melanoma cells do not inhibit (Werkmeister, J. A., Triglia, T., Andrews, P., and Burns, G. F. (1985) J. Immunol. 135, 689-695). Leo Mel 3 binds several different gangliosides from melanoma cells, as determined by immunostaining thin layer chromatograms. Binding is abolished by treatment of the gangliosides with neuraminidase. In solid-phase radioimmunoassay, Leo Mel 3 binds strongly to ganglioside GD2 and less strongly to gangliosides GT3, GD3, and GQ1b. It does not bind to other gangliosides including GM1, GM2, GM3, GD1a, GD1b, and GT1b. Thus, the epitope recognized by antibody Leo Mel 3 is found in the sugar sequence of ganglioside GD2, GalNAc beta 1-4[NeuAc alpha 2-8NeuAc alpha 2-3]Gal beta 1-4Glc beta 1 .... This sequence may contain a target in melanoma cells recognized by AK cells.
