General description

N-Acetyl-D-galactosamine (GalNAc), an amino sugar, is a component of many O-linked and N-linked glycan structures. As uridine diphosphate (UDP)-GalNAc, GalNAc is the initial O-linked sugar to many serine and threonine residues in protein glycosylations.

Application

N-Acetyl-D-galactosamine has been used:
  • as a Dolichos biflorus agglutinin (DBA) haptenic sugar in lectin bead binding assay
  • to assess the specificity of lectin binding using lectin blot inhibition
  • in immunohistochemistry to pre-adsorb Wisteria floribunda lectin
