実験手順

NeuAc (0.92 g, 3 mmol), Galβ1,4GlcNAc (1.1 g, 3 mmol), CMP (0.1 g, 30 μmol), ATP (16 mg, 3 μmol), PEP (2.8 g, 6 mmol), MgCl2.6H2O (0.61 g, 3 mmol), MnCl2.4H2O (0.15 g, 0.8 mmol), KCl (0.22 g, 3 mmol), NMK or MK (450 U), PK (6,000 U), PPase (300 U), CMP-NeuAc synthetase (24 U), and Siaα2,6Gal sialyl transferase (4 U) were mixed with 150 ml of HEPES buffer (0.2M, pH 7.5) to form a reaction mixture and the reaction mixture maintained under argon at about 25° C. for about 48 hours. After the disappearance of NeuAc (determined by thin-layer chromatography) the reaction mixture was reduced in volume to 20 ml by lyophilization and the lyophilized reaction mixture applied to a Bio Gel P2 (200-400 mesh) column with water as the mobile phase. The trisaccharide-containing fractions were eluted, collected and lyophilized to give pure Neuα2,6Galβ1,4GlcNAc in 97 percent yield.
