General description

Deoxyribonuclease I digests single- and double-stranded DNA to a mixture of mono and oligonucleotides carrying 5′phosphates and 3′OH termini. This catalytic activity is divalent ion-dependent.[1] In the presence of Mg2+, DNase I hydrolyzes each strand of double-stranded DNA randomly and independently. In the presence of Mn2+, both strands can be cleaved.

Application

Deoxyribonuclease I RNase-free solution from bovine pancreas has been used to digest DNA from various samples.[2][3][4]
Used in molecular biology applications for removing DNA during RNA purification, for preparing DNA for nick translation, and for DNA-protein interaction analysis by footprinting methods.

Components

DNase I is provided in a solution of 50% (v/v) glycerol, 20 mM sodium acetate (pH 6.5), 5 mM CaCl2, and 0.1 mM PMSF.

Unit Definition

One unit will cause a ΔA260 of 0.001 per min per mL reaction mixture using calf thymus DNA as substrate.

Other Notes

RNA treated with this DNase I should not be used to generate a cDNA library or used for RT-PCR. For these sensitive applications, it is recommended to use DNase I, Amplification Grade , Catalog Number AMP-D1.

Objective: Hypercholesterolemia-induced NETosis and accumulation of neutrophil extracellular traps (NETs) in the atherosclerotic lesion exacerbates inflammation and is causally implicated in plaque progression. We investigated whether hypercholesterolemia additionally impairs the clearance of NETs mediated by endonucleases such as DNase1 and
