PE932000: Galβ(1-3)GalNAc-α-PEG3-Acid

PE932000

Galβ(1-3)GalNAc-α-PEG3-Acid

A core 1 / T antigen (Galβ1-3GalNAcα) 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 presents the core 1 / T antigen (Galβ1-3GalNAcα), a tumor-associated carbohydrate antigen and ligand for galectins and the macrophage galactose lectin, used to build glycopeptides and probes for cancer immunology and O-glycobiology.
