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.

Composants

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
F-6-P 12 mM
Bovine Serum Albumin 5 mg/mL
Sugar Stabilizer 5 mg/mL
PPi-PFK 0.5 units/mL

TPI 50 units/mL

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.

Pretreatment of discs excised from developing tubers of potato (Solanum tuberosum L.) with 10 millimolar sodium fluoride induced a transient increase in 3-phosphoglycerate content. This was followed by increases in triose-phosphate, fructose 1,6-bisphosphate and hexose-phosphate (glucose 6-phosphate + fructose 6-phosphate

Pyrophosphate (PPi) was measured in pea (Pisum sativum L.) and corn (Zea mays L.) tissues by using an enzymic method based on PPi-dependent phosphofructokinase (PPi-PFK). Different organs of pea and corn seedlings were extracted to determine if PPi is present
