Cat. No. : CMC04
Product Overview : DNase I is a glycosylated polypeptide that is commonly used to degrade unwanted single- and double-stranded DNA into 5´phosphodinucleotide and oligonucleotide fragments. The properties of DNase I can be modified by divalent ions. For example, in the presence of Mg2+, Ca2+ or Zn2+, DNase I degrades DNA by making random single-strand nicks in the phosphate backbone. In the presence of divalent transition metals such as Mn2+ or Co2+, DNase I creates double-strand breaks, resulting in fragments with 0-2 nucleotide overhangs. DNase I is suitable for removal of genomic DNA from cell lysates, removal of plasmid from in vitro transcribed RNA, nick translation and DNase I footprinting.
