Application

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.

Actions biochimiques/physiologiques

The pyrophosphate detection kit couples the production of pyrophosphate to the consumption of NADH.

Conditionnement

A technical bulletin is included.

ComponentConcentration
Imidazole × HCl, pH 7.4 45 mM
Citrate 5 mM
EDTA 0.10 mM
Mg2+, Mn2+, Co2+ 2 mM, 0.2 mM, 0.02 mM
β-NADH 0.8 mM

Qualité

A coupled enzyme system containing fructose-6-phosphate kinase (pyrophosphate-dependent), aldolase, triosephosphate isomerase, and α-glycerophosphate dehydrogenase.

Principe

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.

Notes préparatoires

Dissolve the contents of one vial of Pyrophosphate Reagent in 4.0 mL of water.

Cystic fibrosis transmembrane conductance regulator (CFTR) is a chloride channel belonging to the adenosine triphosphate (ATP)-binding cassette (ABC) superfamily. ABC proteins share a common molecular mechanism that couples ATP binding and hydrolysis at two nucleotide-binding domains (NBDs) to diverse functions.
