Digestion of dsDNA


  • Ideal for use in nucleosome mapping studies.
  • Sold separately or as part of EZ Nucleosomal DNA Prep Kit (D5220).


Atlantis dsDNase is a double-stranded DNA-specific endonuclease that cleaves phosphodiester bonds in DNA to yield homogeneous populations of core nucleosomes.

Technical Specifications
