Abstract

The tumor associated Tn (GalNAcα (1-1)-Thr/Ser)-and T (Galβ (1-3)-GalNAcα (1-1) Thr/Ser)- antigens and their sialylated derivatives are present on the surface of many cancer cells. Preparative synthesis of these sialylated T-and Tn-structures has been achieved mainly from a chemical synthetic approach due to the lack of the required glycosyltransferases. We demonstrate a flexible and efficient chemoenzymatic approach for using recombinant ...
