title: Autoradiography of ganglioside antigens separated by high-performance thin-layer chromatography with their antibodies.
abstract: An improved method is described for the detection of ganglioside antigens with the antibodies on thin-layer chromatograms. The method involves the following steps: Separation of gangliosides on a high-performance thin-layer chromatographic plate, application of antibody solution, and detection of bound antibody with [125I]staphylococcal protein A. Using specific antibodies against gangliosides GM4, GM1, GD3, and asialo GM1 ganglioside, the method allowed positive identification of these antigens on thin-layer plates. It also provides a convenient means of assessing the specificity of an anti-glycolipid antibody.
