| Description: | The assay buffer is prepared to give a final concentration of 50 mM H2NaPO3 HNa2PO3, 0.01% bovine serum albumin and 0.01% Triton X-100 in water, at pH 7. Compounds to be tested are diluted in pure dimethyl sulfoxide (DMSO) using ten point concentration response curves. Maximal compound concentration in the reaction mixture is 30 or 1 μM. Compounds at the appropriate concentration are pre-incubated with OGA enzyme for 30 minutes before the reaction is started by the addition of substrate. The final enzyme concentration is 3.24 nM or 0.5 nM, for the 30 or 1 μM maximal compound concentration, respectively. Reactions are allowed to proceed for 60 minutes at room temperature. Then, without stopping the reaction, fluorescence is read. IC50 values are calculated by plotting the normalized data vs. log of the compound and fitting the data using a four parameter logistic equation. |
