Product Overview :
Pyridine nucleotides play an important role in metabolism and, thus, there is continual interest in monitoring their concentration levels. Quantitative determination of NADP+/NADPH has applications in research pertaining to energy transformation and redox state of cells or tissue. Simple, direct and automation-ready procedures for measuring NADP+/NADPH concentration are very desirable. NADP+/NADPH assay kit is based on a glucose dehydrogenase cycling reaction, in which the formed NADPH reduces a formazan (MTT) reagent. The intensity of the reduced product color, measured at 565 nm, is proportionate to the NADP+/NADPH concentration in the sample. This assay is highly specific for NADP+/NADPH and is not interfered by NAD+/NADH. Our assay is a convenient method to measure NADP, NADPH and their ratio.
Detection method :
OD565nm
Compatible Sample Types :
Cell, tissue extracts etc
Features & Benefits :
Sensitive and accurate. Detection limit 0.1 μM, linearity up to 10 μM NADP+/NADPH in 96-well plate assay.
Convenient. The procedure involves adding a single working reagent, and reading the optical density at time zero and 30 min at room temperature. No 37°C heater is required.
High-throughput. Can be readily automated as a high-throughput 96-well plate assay for thousands of samples per day.
