一般描述

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.

应用

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)

生化/生理作用

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.

分析说明

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

α-Toxin, a major determinant of Clostridium perfringens toxicity, exhibits both phospholipase C and sphingomyelinase activities. Our studies with large unilamellar vesicles containing a variety of lipid mixtures reveal that both lipase activities are enhanced by cholesterol and by lipids with
