Query String: GSNO

GSNOR Assay GSNO and Enzyme/NADH Solutions are made up fresh each day. The Solutions are filtered and allowed to warm to room temperature. GSNO Solution: 100 mM NaPO4 (pH 7.4), 0.480 mM GSNO. 396 μL of GSNO Solution is added to a cuvette followed by 8 μL of test compound in DMSO (or DMSO only for full reaction control) and mixed with the pipette tip. Compounds to be tested are made up at a stock concentration of 10 mM in 100% DMSO. 2 fold serial dilutions are done in 100% DMSO. 8 μL of each dilution are added to an assay so that the final concentration of DMSO in the assay is 1%. The concentrations of compounds tested range from 100 to 0.003 μM. Enzyme/NADH Solution: 100 mM NaPO4 (pH 7.4), 0.600 mM NADH, 1.0 μg/mL GSNO Reductase. 396 μL of the Enzyme/NADH Solution is added to the cuvette to start the reaction.
