Pyrophosphatase, Inorganic (from yeast)

LO certified Not inactivated at 80°C in 20 min Recombinant enzyme

Pyrophosphatase, Inorganic catalyzes the hydrolysis of inorganic pyrophosphate to two orthophosphates.
  
Loading...
Thermo Scientific Pyrophosphatase, Inorganic catalyzes the hydrolysis of inorganic pyrophosphate into two orthophosphates (see Figure 1 in Supporting data). The enzyme requires a divalent metal cation with Mg2+ conferring the highest activity (see Reference 1).

Highlights

Applications

  • High yield RNA synthesis by in vitro transcription (see Reference 2)
  • DNA polymerization reactions: preventing accumulation of pyrophosphate (see References 3, 4)
  • Removal of contaminant PPi in reagents used for SNP genotyping by methods based on the detection of pyrophosphate (see Reference 5)

Note

The enzyme can be diluted with the supplied storage (dilution) buffer. Use of this enzyme in certain applications may be covered by patents and may require a license.
