Pyrophosphatase, Inorganic, GMP-Grade (GMP-PYR-YE101), DMF #038030 Summary
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. |
