Journal Article

A monoclonal antibody produced by immunization with cells of the human glioma cell line D-54 MG reacted with ganglioside GM2. The binding epitope of the antibody was found to be GalNAc beta 1-4(NeuAc alpha 2-3)Gal. Immunological detection of glycolipid antigens on thin-layer plates with this monoclonal antibody, DMAb-1, revealed the presence of a new ganglioside. This ganglioside, co-migrating with NeuAc alpha 2-6Gal beta 1-4GlcNAc beta 1-3Gal beta 1-4Glc beta 1-1Cer(6'-LM1) and GalNAc beta 1-4(NeuAc alpha 2-3)Gal beta 1-3GalNAc beta 1-4Gla beta 1-4Glc beta 1-1Cer (GalNAc-isoGM1) at chromatographic separation was isolated from human meconium. Its structure was determined by permethylation and fast atom bombardment-mass spectometry analyses. The new ganglioside was found to be a combination of the lacto and ganglio series gangliosides, and the structure found to be GalNAc beta 1-4(NeuAc alpha 2-3)Gal beta 1-3GlcNAc alpha 1-3Gal beta 1-4Glc beta 1-1Cer(GalNAc-3'-isoLM1).
