PE942000: β-Lac-PEG4-Acid label-new / Fmoc-Ser((Ac)3-Fuc-β-L)-OH / Fmoc-Ser(β-L-Fuc)-OH (Peracetate)C21H38O16 546. 52 A D lactose ligand equipped with a terminal carboxylic acid through a hydrophilic PEG4 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 a lactose (Gal1 4Glc) building block for glycoconjugate synthesis and the construction of probes for galactose recognizing
