A3 Glycan (A3G3S3)，Triantennary N-glycan that contains terminal sialic acid residues.
A3 Glycan Synonyms: A3 N-linked oligosaccharide, A3G3S3
Description: Tri-sialylated, tri-antennary complex-type N-glycan (oligosaccharide). The product supplied is a mixture of isomers differing in the type of sialic acid linkages (Neu5Acα2-3 or Neu5Acα2-6) and the Gal residue linkage of one of the arms (Galβ1-4 or Galβ1-3).
Molecular Weight: 2879
Purity: > 90% pure as assessed by a combination of 1 H-NMR and HPLC.
Sources: A3 glycans are found on several mammalian glycoproteins including bovine serum fetuin (bSF). This product is typically purified from the oligosaccharide pool released from bSF by hydrazinolysis using a combination of HPLC and glycosidase digestion.
Form: Dry. Dried by centrifugal evaporation from an aqueous solution containing approximately 50 mmol dm-3 of ammonium acetate (added to minimize acid-catalysed desialylation).
