Application Notes:
This product contains the disialogangliosides GD3, GD1a, and GD1b in approximately equal amounts. It is a qualitative
mixture prepared from highly pure materials and is in chloroform/methanol/water (2:1:0.1). The defining characteristic of
gangliosides is the sialic acid moiety of the oligosaccharide head group. This mixture contains gangliosides having two sialic
acids. Gangliosides1 are acidic glycosphingolipids that form lipid rafts in the outer leaflet of the cell plasma membrane,
especially in neuronal cells in the central nervous system.2 They participate in cellular proliferation, differentiation, adhesion,
signal transduction, cell-to-cell interactions, tumorigenesis, and metastasis.3 The accumulation of gangliosides has been
linked to several diseases including Tay-Sachs and Sandhoff disease while an autoimmune response against gangliosides can
lead to Guillain-Barré syndrome. Gangliosides act as receptors for various toxins and bacteria, accumulate in different
tumors, and aid in many neuronal functions. Therefore they are very important in therapeutic processes. This is a qualitative
mixture and should not be used for quantitative purposes.
