실험 절차

In a 10 mL of 0.1M potassium phosphate buffer (pH 7.5) containing 10 mM DTT and 0.5M pyruvate were dissolved 50 mg of 6-azido-6-deoxy-N-acetylmannosamine and 1.5 mg of NeuAc aldolase. The starting material was consumed in 14 hours. The solution was lyophilized and the purification was carried out with Bio Gel P-2 gel filtration (3×90 cm) chromatography with a flow rate of 6 mL/40 minutes, at 4° C. The fractions containing the product were pooled and freezed dry to give Compound 203 in 84 percent yield.
