PE935000: β-Lac-PEG3-Thiol label-new 69 / / 25-Hydroxy VitaminC18H34O13S 490. 52 A D lactose ligand equipped with a free thiol through a hydrophilic PEG3 spacer. The thiol reacts with maleimides to form stable thioether conjugates or with other thiols to form disulfide bonds; it is also compatible with thiol gold chemistry for surface immobilization. This compound provides a lactose (Gal1 4Glc) building block for glycoconjugate synthesis and the construction of probes for galactose recognizing proteins,
