Description

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. 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.[1]

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.

Other Notes

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.

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

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.
