| Description: | Standard ALDH2 reaction mixtures contained 150 uM formaldehyde, 2.5 mM NAD+, 10 mM MgCl2 and 10 nM recombinant human ALDH2 in 50 mM Hepes buffer, pH 7.4, 0.01% Tween 20 in a final volume of 50 ul using 384-well plates. After 60 min of pre-incubation of compound with ALDH2 and formaldehyde, the reaction was started by adding NAD+ and the reaction mixture was allowed to proceed for 90 minutes. Activity of the enzyme was determined by monitoring NADH formation using Perkin-Elmer Envision Reader with excitation and emission wavelengths set at 340 and 460 nm, respectively. |
