C16 Ganglioside GM1-d9 (d18:1/16:0-d9) (ammonium salt)

C16 Ganglioside GM1-d9 (d18:1/16:0-d9) is intended for use as an internal standard for the quantification of C16 ganglioside GM1 by GC- or LC-MS. Ganglioside GM1 is a monosialylated ganglioside and the prototypic ganglioside for those containing one sialic acid residue. C16 Ganglioside GM1 (d18:1/16:0) is a monosialylated ganglioside that contains a 16-carbon saturated acyl chain. It has been found in the brain of wild-type mice and mice lacking the gene for alpha-N-acetylneuraminide alpha-2,8-sialyltransferase (St8sia1null) but not those lacking the gene for beta-1,4-N-acetylgalactosaminyltransferase 1 (B4galnt1null). As this product is derived from a natural source, there may be variations in the sphingoid backbone. [Matreya, LLC.
