Descripción general

Gangliosides are sialic acid-containing oligoglycosylceramides. The German scientist Ernst Klenk used the term ganglioside in 1942 to refer to lipids isolated from ganglions. Gangliosides are grouped based on the number of sialic acid residues per molecule, GM gangliosides contain one sialic acid residue, GD gangliosides contain two, GT contain three, GQ contain four sialic acid residues. Glycolipids constitute >80% of mammalian brain glycans, with gangliosides being the major glycans in nerve cells. Among the hundreds of ganglioside structures, GM1a, GD1a, GD1b and GT1b comprise up to 97% of gangliosides in the human brain. These four gangliosides share the same neutral tetrasaccharide core (Galβ1-3GalNAcβ1-4Galβ1-4Glcβ1-1′Cer), but differ from each other by their sialic acid residue(s). GM1a and GD1b contain one or two sialic acids on the internal galactose, respectively, and no sialic acid on the terminal galactose. The St3gal2 and St3gal3 gene products (ST3Gal-II and ST3Gal-III sialyltransferase, respectively) are largely responsible for ganglioside terminal α2-3 sialylation of GM1a and GD1b to produce GD1a and GT1b in the brain. Brain GD1a and GT1b in St3gal2-null mice is about half the level in wild-type mice, while GD1a and GT1b level in St3gal2/3-double-null mice is less than 5% of the level in wild-type mice. St3gal2/3-double-null mice are half the weight of wild-type mice at weaning and display early hindlimb dysreflexia.

Especificidad

GD1a ganglioside. The antibody shows approximately 10% reactivity to GalNAc-GD1a and GT1aα. Preferentially binds to motor myelinated fibers in cross-sections of ventral roots and sciatic nerves.

Inmunógeno

KLH-conjugated GD1a ganglioside.

Aplicación

Anti-GD1a Ganglioside Antibody, clone GD1a-1 (Azide Free) is an antibody against GD1a Ganglioside for use in Immunohistochemistry (Paraffin) and Enzyme Immunoassay (ELISA).
Immunohistochemistry Analysis: A 1:50 dilution from a representative lot detected GD1a Ganglioside in human prostate tissue.
ELISA Analysis: Target specificity of a representative lot was determined by ELISA analysis (Gong, Y., et al. (2002). Brain. 125(Pt 11):2491-2506).
Immunohistochemistry Analysis: A representative lot detected GD1a immunoreactivity in fresh-frozenmid-sagittal brain sections from wild-type and St3gal2/3-double-null mice (Sturgill, E.R., et al. (2012). Glycobiology.22(10):1289-1301).
Immunohistochemistry Analysis: A representative lot detected GD1a immunoreactivity in various fish brain regions using free-floating sections (Viljetić, B., et al. (2012). Biochim Biophys Acta. 1820(9):1437-1443).
Immunohistochemistry Analysis: A representative lot detected GD1a in fresh-frozen human and rat brain sections by both fluorescent and non-fluorescent immunohistochemistry (Gong, Y., et al. (2002). Brain. 125(Pt 11):2491-2506).
Immuno-overlay Assay: A representative lot detected bovine brain GD1a, as well as GD1a in human ventral and dorsal root gangliosides extracts (Gong, Y., et al. (2002). Brain. 125(Pt 11):2491-2506).

As part of a systematic investigation of the glycosphingolipids in human tissues, acid and non-acid glycosphingolipids from human thyroid and parathyroid glands were isolated and characterized with mass spectrometry and binding of carbohydrate-recognizing ligands, with a focus on complex compounds.

High expectations are held for human-induced pluripotent stem cells (hiPSC) since they are established from autologous tissues thus overcoming the risk of allogeneic immune rejection when used in regenerative medicine. However, little is known regarding the cell-surface carbohydrate antigen profile

Gangliosides are acidic glycosphingolipids, containing ceramide moieties and oligosaccharide chains with one or more sialic acid residue(s) and are highly diverse isomeric structures with distinct biological roles. Matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI IMS) enables the untargeted spatial analysis

Journal of neuroinflammation, 19(1), 9-9 (2022-01-08)
Gangliosides are glycosphingolipids highly enriched in the brain, with important roles in cell signaling, cell-to-cell communication, and immunomodulation. Genetic defects in the ganglioside biosynthetic pathway result in severe neurodegenerative diseases, while a partial decrease in the levels of specific gangliosides
