PE933000: β-Lac-PEG3-Amine label-new 39 / A 4-nitrophenyl α-glycosideC18H35NO13 473. 47 A D lactose ligand equipped with a primary amine through a hydrophilic PEG3 spacer. The amine couples with NHS activated esters to form stable amide bonds, providing a route to conjugate the ligand onto NHS activated molecules and surfaces. This compound provides a lactose (Gal1 4Glc) building block for glycoconjugate synthesis and the construction of probes for galactose recognizing proteins, including galectins and the hepatic
