PE934000: β-Lac-PEG3-Azide label-new Glcα(1-4)Glc-PEG4-COOHC18H33N3O13 499. 5 A D lactose ligand equipped with an azide handle through a hydrophilic PEG3 spacer. 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, forming stable 1,2,3 triazole linkages. This compound provides a lactose (Gal1 4Glc) building block for glycoconjugate synthesis and the construction of probes for galactose recognizing
