Product Information
Description
Highlights
Isolated from a recombinant sourceSupplied with 10X Reaction Buffer DNase I, (RNase-free) is an endonuclease that nonspecifically cleaves DNA to release di-, tri- and oligonucleotide products with 5´-phosphorylated and 3´-hydroxylated ends (1,2). DNase I acts on single- and double-stranded DNA, chromatin and RNA:DNA hybrids.

Product Notes
- EDTA should be added to a final concentration of 5 mM to protect RNA from being degraded during enzyme inactivation (3).
- We do not recommend using NEB's DNase I as a substitute for Monarch DNase I in the RNA isolation workflow when using the Monarch Total RNA Miniprep Kit (NEB #T2010). Monarch DNase I is optimized for use in this workflow, and is available for purchase as a component of the Monarch Total RNA Enzyme Pack, (NEB #T2019).
