A combined sequential use of beta-galactosidase from bovine testes together
with alpha 2-3-sialyltransferase from porcine liver including cofactor reg
eneration transforms GalNAc alpha 1-OThr by a multistep one-pot reaction in
to the sialylated Thomsen-Friedenreidh antigen determinant Neu5Ac alpha 2-3
Gal beta 1-3GalNAc alpha 1-OThr.
