The C- terminus is an amide
T Antigen (Serine
/ α-D-GalNAc-Ser-NH-Biotin / Biotinyl Tn Antigen (Serine)
6) Asn-PEG8-Biotin (extended tri-LacNAc arms)
GA230000: H-Thr(GlcNAc-β-D)-OH Pack Size:5 mg The C- terminus is anC12H22N2O8 322. 31 A fully unprotected (free amine, free acid) L threonine glycoamino acid carrying a D GlcNAc 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 O GlcNAc (GlcNAc O Ser Thr), the intracellular monosaccharide modification central to O GlcNAcylation signaling, used to build O GlcNAc
