GA121030: Fmoc-Ser(Galβ(1-3)(GlcNAcβ(1-6))GalNAc-OH (Peracetate) Pack Size:25 mg Tri-GalNAc-β-Ala-PEG3-BiotinC56H69N3O28 1232. 15 An Fmoc protected L serine building block carrying a branched Gal1 3[GlcNAc1 6]GalNAc trisaccharide, 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 acetate esters (peracetate),
