Ganglioside GD2 is a glycosphingolipid that contains two sialic acid residues linked to an inner galactose unit. It is frequently expressed on tumor cells of neuroectodermal origin, including neuroblastomas.[1] This product contains ganglioside GD2 molecular species with primarily C18:0 fatty acyl chain lengths. As this product is derived from a natural source, there may be variations in the sphingoid backbone.
