Preparation and specificity of 11 monoclonal antibodies to GM1 ganglioside.
Eleven monoclonal antibodies to GM1 ganglioside were prepared from hybridoma clones obtained by fusion of spleen cells from mice immunized with GM1 with mouse myeloma cells. When the reactivities of these 11 monoclonal antibodies were determined by enzyme-linked immunosorbent assay with six glycosphingolipids (GM1, GD1a, GD1b, GT1b, GM2, and asialo-GM1), they showed different degrees of specificity. From their reactivity patterns, they could be divided into three groups: Group 1, those that react only with GM1 (C3 and D3); Group 2, those that react predominantly with GM1 (C6, B6, D1, e1, g1, g9, and e12); and Group 3, those that show poor discrimination (h2 and A4). The clones differed in their biological activities.
