GA134000: Ac-Thr(α-Galβ(1-3)GalNAc)-OCH3 Pack Size:2 mg biosynthesis substrateC21H36N2O14 540. 52 An N acetyl, C terminal methyl ester L threonine glycoamino acid carrying a Gal1 3GalNAc disaccharide (T antigen). Both termini are capped, making this a self contained model compound for conformational, analytical, or enzymatic studies rather than a chain extendable SPPS building block. The installed glycan is the T antigen core 1 structure (Gal1 3GalNAc O Ser Thr), a tumor associated carbohydrate antigen and ligand for galectins
