Product Description | Pyrophosphatase hydrolyzes inorganic pyrophosphate generated during in vitro transcription reactions. By removing unwanted pyrophosphate, the equilibrium is shifted to the product side increasing RNA yield. NOTE: A PH 7.0 is ideal for optimal performance and the cofactor Mg2+ is required for enzymatic activity. This product has been filed with the FDA Drug Master Files (DMF) and is assigned DMF #038030. |
Application | In vitro transcription (IVT) |
Concentration | 0.1U/µL |
Unit Definition | One unit is the amount of enzyme that will generate 1µmol of phosphate per minute from inorganic pyrophosphate under standard reaction conditions (a 10 minute reaction at 25°C in 100 mM Tris-HCl, [pH 7.2], 2 mM MgCl2 and 2 mM PPi in a reaction volume of 0.5 mL). |
Source | Expressed in an E.coli strain with the pyrophosphatase gene from yeast. |
