产品说明
应用
The product has been used for the measurement of pyrophosphate content of plant tissues. It has also been used as a rapid, routine check of pyrophosphate content by monitoring NADH oxidation in Solanum tuberosum tuber extracts.
生化/生理作用
The pyrophosphate detection kit couples the production of pyrophosphate to the consumption of NADH.

质量
A coupled enzyme system containing fructose-6-phosphate kinase (pyrophosphate-dependent), aldolase, triosephosphate isomerase, and α-glycerophosphate dehydrogenase.
原理
Two moles of NADH are oxidized to NAD+ per mole of pyrophosphate consumed. The reaction is monitored spectrophotometrically at 340 nm.
The reagent can be used to detect 10-100 nmoles of pyrophosphate.
制备说明
Dissolve the contents of one vial of Pyrophosphate Reagent in 4.0 mL of water.
