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.
Deoxyribonuclease (DNase) I Solution (1 mg/mL) is useful to reduce or prevent the clumping of concentrated and/or cryopreserved cell suspensions following thawing.
