GalNAc-PEG5K-Thiol
HBB(2-7) Fructose analogue (at Valine)
The terminal azide couples to alkynes via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or to DBCO and related strained alkynes via copper-free click chemistry
8 / A triantennary N-acetylgalactosamine (Tri-GalNAcβ) ligand presenting three β-GalNAc residues on a tris-based branched scaffold
PE932020: β-LacNAc-PEG3-Acid Pack Size:10 mg GalNAc-PEG5K-ThiolC21H37NO15 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
