GA120000: H-Ser(α-D-GalNAc)-OH Pack Size:2 mg α-L-Rha-Bu-CO2HC11H20N2O8 308. 29 A fully unprotected (free amine, free acid) L serine glycoamino acid carrying an D GalNAc residue. This deprotected building block is suited to use as a reference standard, an enzymatic substrate acceptor, or for conjugation and analytical work rather than direct Fmoc SPPS. The installed glycan is the Tn antigen (GalNAc O Ser Thr), the simplest mucin type O glycan and a tumor associated carbohydrate antigen, widely used to build
