General description

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)

Biochem/physiol Actions

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.

Analysis Note

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 abundant in neural tissue and play important roles in cell-cell adhesion, signal transduction, and cell differentiation. Gangliosides are divided into 4 groups: asialo-, a-, b-, and c-series gangliosides, based on their biosynthetic pathway. St8sia1 knockout mice, which lack

Since gangliosides play many important roles in neural systems, we investigated whether gangliosides are involved in glutamate release from neural cells. Differentiated neruro2a cells were treated with gangliosides, including GM3, GM1, GD1a, GD3, GD1b, or GT1b, for 30 min, and
