/ β-Mal-PEG4-Acid / β-Mal-PEG4-COOH
PE435000: β-Gal-PEG3-Thiol label-new Sialyl Tn or STn (Neu5Acα2-6GalNAcα-O-Ser)C12H24O8S 328. 38 A D galactose 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 anomeric galactose building block for glycoconjugate synthesis, glycomimetic research, and the construction of probes for galactose
