PE132010: β-GalNAc-PEG3-Acid label-new structurally defined HS/heparin fragments areC15H27NO10 381. 38 A D N acetylgalactosamine (GalNAc) ligand equipped with a terminal carboxylic acid through a hydrophilic PEG3 spacer. The carboxylic acid can be activated to NHS, sulfo NHS, or pentafluorophenyl esters and reacted with amine functionalized platforms or lysine residues on proteins and peptides to form amide bonds. This compound enables the construction of hepatocyte targeted therapeutics and research tools that exploit the
