Dnase I, Rnase-free is an endonuclease that digests single- and double-stranded DNA. It hydrolyzes phosphodiester bonds producing mono- and oligodeoxyribonucleotides with 5'-phosphate and 3'-OH groups.

The enzyme activity is strictly dependent on Ca2+ and is activated by Mg2+ or Mn2+ ions.

  • In the presence of Mg2+, Dnase I cleaves each strand of dsDNA independently in a statistically random fashion.
  • In the presence of Mn2+, the enzyme cleaves both DNA strands at approximately the same site, producing DNA fragments with blunt-ends or with overhang termini of only one or two nucleotides.


  • Recombinant enzyme
  • Purified from non-animal host with a lower level of intrinsic RNases
