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)
