DNase I Set, RNase-free

DNase I Set, RNase-free

Highly Efficient on-column digestion of DNA

Product Overview:

On-membrane DNase I Set (RNase-Free) is designed for a highly efficient on-column digestion of DNA during critical RNA purification procedures for downstream applications requiring DNA-free total RNA.
DNase I, RNase free, recombinant, is an endonuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide, to release di-, tri-, and oligonucleotide products (on average producing tetranucleotides) with 5′-phosphorylated and 3′-hydroxylated ends. DNAse I acts on single-stranded DNA, double-stranded DNA, RNA-DNA hybrids, and chromatin. DNase I requires bivalent cations (Mg2+ and Ca2+) for maximal activity.

Advantages & Features

  • Highly Efficient on-column digestion of DNA thanks to its innovative OM Buffer composition that ensures that the RNA remains bound to the column.
  • RNAse-free.
  • Recombinant Bovine Pancreatic DNAse I, purified from coli (29 kDa monomer).
  • Optimized Buffer included for on-column DNase digestion.


  • Unit Definition: One Kunitz unit is defined as the amount of DNase I that causes an increase in A260 of 0.001 per minute per ml at 25 °C, pH 5.0, with highly polymerized DNA as substrate.


Includes for 50 preps:

– 500 μL DNase I (1500 Kunitz units)

– 2 x 2 mL OM Buffer*

* Standard DNase Buffers are not compatible with On-Column DNase digestion. The usage of other buffers may affect the binding of RNA to the Spin Column membrane, reducing RNA yield and integrity.
