GA511000: Fmoc-Asn(Glc(Ac)4-β-D)-OH Pack Size:500 mg Sialyl Tn or STn (Neu5Acα2-6GalNAcα-O-Ser)C33H36N2O14 684. 64 An Fmoc protected L asparagine building block carrying a D glucose residue, designed for solid phase peptide synthesis (SPPS) of glycopeptides. The N Fmoc group is removed under standard base conditions (piperidine) during chain elongation, while the free carboxylic acid is available for coupling to the growing resin bound peptide. The sugar hydroxyl groups are protected as four acetate esters (Ac4), which keep the glycan inert
