| | Enzyme Activity Assay (pH=5.9) |
| Description: | The compounds in DMSO solution (0.5 μL/well) were transferred to a black 96-well plate (the final titration started from 100 μM, a 12 or 24-point 2-fold dilution series). Enzyme solution (33.5 μL, 7.5 nM final concentration, in pH 5.9 buffer) was transferred to the wells. After 5 min of incubation at room temperature, the enzyme reaction was initiated by the addition of blue substrate (4MU-β-Glc) (33 μL/well). The final concentration of the blue substrate was 1.5 mM. The blue substrate reaction was terminated by the addition of 33 μL/well stop solution (1 M NaOH and 1 M glycine mixture, pH 10) after 30 min of incubation at 37° C. The fluorescence was then measured in a Biotek Synergy H1 multi-mode plate reader with Ex=365 nm and Em=440 nm. The selected compounds were further assayed under pH 5.9 to evaluate their selectivity under various pH conditions. |
