PE932020: β-LacNAc-PEG3-Acid label-new C54H92N18O26 / 1409C21H37NO15 543. 52 A D N acetyllactosamine (LacNAc) 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 provides an N acetyllactosamine (LacNAc; Gal1 4GlcNAc) building block, a core disaccharide of N and O glycans
