产品概述
NADP/NADPH Assay Kit (ab65349) provides a convenient tool for sensitive detection of the intracellular nucleotides: NADP, NADPH and their ratio. Assays of nicotinamide nucleotides are of continual interest in the studies of energy transforming and redox state of cells or tissue.
The enzymes in the system specifically recognize NADP/NADPH in an enzyme cycling reaction. The assay does not recognize NAD+/NADH. There is no need to purify NADP/NADPH from the sample mix. The enzyme cycling reaction significantly increases detection sensitivity. Results can be quantified using a plate reader at OD450nm.
NADP / NADPH assay protocol summary:
- extract samples from cells / tissues with extraction buffer and deproteinize with spin column
- for NADPH measurement, heat samples to 60ºC for 30 min to decompose NAD+, cool on ice (this step not necessary for measurement of total NADP+/NADPH)
- add samples and standards to wells
- add reaction mix and incubate for 5 min at room temp to convert NADP to NADPH
- add NADPH developer and incubate for 1-4 hrs while reaction cycles
- analyze with microplate reader multiple times during the 1-4 hr incubation
- reaction can be stopped with stop solution

NADP (Nicotinamide adenine dinucleotide phosphate) is a coenzyme composed of ribosylnicotinamide 5-phosphate (NMN) coupled by pyrophosphate linkage to the 5-phosphate adenosine 2,5-biphosphate. It serves as an electron carrier in a number of reactions, being alternately oxidised (NADP+) and reduced (NADPH). The oxidative phase of the pentose phosphate pathway is the major source of NADPH in cells, producing approxiamtely 60% of the NADPH required. NADPH provides the reducing equivalents for biosynthetic reactions and the oxidation-reduction involved in protecting against the toxicity of ROS, allowing the regeneration of GSH. NADPH is also used for anabolic pathways, such as lipid synthesis, cholesterol synthesis and fatty acid chain elongation.
