The reaction was followed by acquiring 1D NMR experiments at 15-min intervals over 24 h. In the event you liked this article and also you would like to get more details with regards to manufacturer of sialic acid powder for drink Ingredients i implore you to go to our website. All 1D NMR experiments were performed using a Bruker Advance I 500-MHz spectrometer with a 5-mm PATXI 1H/D-13C/15N Z-GRD probe at 293 K. To follow the kinetics of the reaction and assess the position of deuteration, two samples containing 2 mm 2,7-anhydro-Neu5Ac, 100 μm NADH, and 60 μm RgNanOx were used, one in deuterated PBS buffer (PBS/D2O) and one in standard PBS buffer (PBS/H2O, containing 10% D2O for locking purposes). Fractions were pooled and concentrated using a 10,000 molecular weight cut-off Vivaspin column (Vivaspin, Germany).
