NADP/NADPH-Glo™ Assay Technical Manual
Literature # TM400
The NADP/NADPH-Glo™ Assay is a bioluminescent homogeneous assay for detecting total oxidized and reduced nicotinamide adenine dinucleotides phosphates (NADP+ and NADPH, respectively) and determining their ratio in biological samples. In the presence of NADP+ and NADPH, the enzyme Reductase reduces a proluciferin reductase substrate to form luciferin. Luciferin then is quantified using Ultra-Glo™ Recombinant Luciferase, and the light signal produced is proportional to the amount of NADP+ and NADPH in the sample. The assay has a linear range of 10nM to 400nM NADP+ and high signal-to-background ratios and is specific for the phosphorylated forms. The assay is compatible with 96-, 384-, low-volume 384- and 1536-well plates and is well suited to monitor the effects of small molecule compounds on NADP+ and NADPH levels in enzymatic reactions or directly in cells in high-throughput formats.
