The tetraacetylated N-Azidoacetyl-galactosamine (Ac4GalNAz) is an azide-labeled monosaccharide that provides a highly specific tool for studying glycoproteins through metabolic labeling in vivo and subsequent chemoselective ligation.
Ac4GalNAz is cell-permeable unnatural sugar that is intracellularly processed and incorporated instead of its natural monosaccharide counterpart N-Acetylgalactosamine (GalNAc).
The resulting azide-contained glycoprotein can be detected via Cu(I)-catalyzed (CuAAC) or copper-free (SPAAC) click reaction with either fluorescent-labeled alkynes /cycloalkynes or biotin-alkyne .
The recommended concentration for cell labeling is 25-75 μM, and this concentration range may be a starting point for an individual experiment setup.
