Deoxyribonuclease I(1000u/mg) Supplier



Deoxyribonuclease I (DNase I) is a single, glycosylated polypeptide that degrades unwanted single- and double-stranded DNA. The enzyme works by cleaving DNA into 5' phosphodinucleotide and small oligonucleotide fragments. DNase I is commonly added to cell lysis reagents to remove the viscosity caused by the DNA content in bacterial cell lysates or to remove the DNA templates from RNAs produced by in vitro transcription. Two grades of DNAse are offered, one sufficient for protein work and one that is useful for any application requiring the digestion of DNA in which it is crucial to avoid damage to RNA.
