Description générale

Gangliosides are major constituents of neuronal cell membranes and endoplasmic reticulum. They contain a sialated polysaccharide chain linked to ceramide through a β-glycosidic linkage. For classification of gangliosides see Svennerholm, L., et al. (eds.), Structure and Function of Gangliosides, New York, Plenum, 1980.

Application

Trisialoganglioside-GT1b from bovine brain has been used:
  • in high performance thin layer chromatography (HPTLC)
  • in membrane GM1 assays
  • as reference standards for TLC (thin layer chromatography) and as antigens for ELISA (enzyme-linked immunosorbent assay)

Actions biochimiques/physiologiques

Ganglioside marker for metastatic brain tumors. Modulates cellular differentiation; prevents glutamate neurotoxicity; inhibits mitogenesis stimulated by lectins such as Con A. Converted to GD1b by bacterial and mammalian sialidases.

Remarque sur l'analyse

Homogeneous aqueous preparations can be obtained by suspending the compound in water, buffer or cell culture medium and sonicating briefly to facilitate the micelle formation.

Gangliosides are lipophilic compounds found in cell plasma membranes throughout the brain that play a role in neuronal plasticity and regeneration. Indeed, absence or abnormal accumulation of gangliosides has been shown to lead to neurological disorders. Experimental data have shown
