| 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 |
