Fluorinated Thomsen–Friedenreich (T) antigens were synthesized efficiently from chemically produced fluorinated monosaccharides using a highly efficient one-pot two-enzyme chemoenzymatic approach containing a galactokinase and a D-galactosyl-β1–3-N-acetyl-D-hexosamine phosphorylase. These fluorinated T-antigens were further sialylated to form fluorinated ST-antigens using a one-pot two-enzyme system
氟化 Thomsen-Friedenreich (T) 抗原是使用含有半乳糖激酶和D-半乳糖基-β1-3- N-乙酰-D-己糖胺磷酸化酶的高效一锅双酶化学酶法从化学生产的氟化单糖有效合成的。使用含有 CMP-唾液酸合成酶和 α-2-3-唾液酸转移酶的一锅双酶系统将这些氟化 T 抗原进一步唾液酸化以形成氟化 ST 抗原。

and cis-diol-containing biomolecules. Therefore, a widely applicable method is still greatly needed. In this work, an affinity capillary electrophoresis (ACE) method was established and validated to probe the interactions between boronic acids and cis-diol-containing biomolecules. The method was proven to be applicable to almost all types of cis-diol-containing biomolecules and boronic acids. Based
