GANGLIOSIDE GD1A DISODIUM SALT Usage And Synthesis

Description

Ganglioside G_D1a is a sialic acid-containing glycosphingolipid found in brain, erythrocytes, bone marrow, testis, spleen, and liver. It can be shed from the surface of tumor cells into the microenvironment where it influences tumor-host cell interactions to promote tumor cell proliferation, invasion, and metastasis. Ganglioside G_D1a (20 μM) also increases endothelial cell proliferation. Furthermore, ganglioside G_D1a has been shown to act as a functional coreceptor for toll-like receptor 2 (TLR2), enabling the recruitment of TLR2 to lipid rafts when bound by a bacterial toxin. Ganglioside G_D1a mixture contains ganglioside G_D1a molecular species with C18:1 and C20:1 sphingoid backbones.

Chemical Properties

White powder

Uses

Ganglioside GD1a Disodium Salt is an agent with a stimulatory effect on phagocytosis and phagosome-lysosome.

General Description

Ganglioside GD1a is an anionic brain ganglioside. It is localized in the inner and outer membrane of nuclear envelope of the neuronal cells. GD1a contains a neutral tetrasaccharide core, with one or two sialic acid on the internal galactose. It also has an additional sialic acid on the non-reducing terminal of galactose.
