NADH Assay
Amplite™ Fluorimetric NADH Assay Kit *Red Fluorescence*
Nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADP+) are two important cofactors found in cells. NADH is the reduced form of NAD+, and NAD+ is the oxidized form of NADH. It forms NADP with the addition of a phosphate group to the 2' position of the adenyl nucleotide through an ester linkage. NADP is used in anabolic biological reactions, such as fatty acid and nucleic acid synthesis, which require NADPH as a reducing agent. In chloroplasts, NADP is an oxidizing agent important in the preliminary reactions of photosynthesis. The NADPH produced by photosynthesis is then used as reducing power for the biosynthetic reactions in the Calvin cycle of photosynthesis. The traditional NAD/NADH and NADP/NADPH assays are done by monitoring of NADH or NADPH absorption at 340 nm. This method suffers low sensitivity and high interference since the assay is done in the UV range that requires expensive quartz microplate. This Amplite™ NADH Assay Kit provides a convenient method for sensitive detection of NADH. The enzymes in the system specifically recognize NADH in an enzyme cycling reaction. The enzyme cycling reaction significantly increases detection sensitivity.
Key Features
Broad Application: Can be used for quantifying NADH in solutions, in cell extracts.
Sensitive: The kit detect as low as 10 nanomoles of NADH in solution.
Continuous: Easily adapted to automation with no separation required.
Convenient: Formulated to have minimal hands-on time. No wash is required.
Non-Radioactive: No special requirements for waste treatment.
Kit Components
Component A: NADH recycling enzyme mixture 2 bottles (lyophilized powder)
Component B: NADH assay buffer 1 bottle (20 ml)
Component C: NADH standard 1 vial (142 μg)
Brief Summary
→ Prepare NADH reaction mixture (50 μL)
→ Add NADH standards or test samples (50 μL)
