  • NAME

    DNase I
  • DESCRIPTION

    Deoxyribonuclease I
  • TAG

    His-tag

Introduction

DNase I is an endonuclease that can digest single- or double-stranded DNA to produce single-nucleotide or single/double-stranded oligonucleotides. The product of DNase I hydrolyzed single or double stranded DNA, contains 5'-terminated phosphate group, 3'-terminated hydroxyl group.
DNase I activity is calcium dependent and can be activated by magnesium or divalent manganese ions. In the presence of magnesium ion, DNase I can randomly shear any site of double-stranded DNA. In the presence of divalent manganese ions, DNase I can cut DNA double strands at the same site to form flat ends, or sticky ends with 1-2 nucleotide protrsions.

Source

Expressed, purified from Cell-Free System of Protein Factory 1.0

Application

It can be used for hydrolysis of DNA.

Formulation

Solution supplied with 50% glycerol.

Activity Definition

The amount of enzyme required to degrade 1 μg plasmid DNA at 37 ℃ for 10 min was defined as one active unit.

Usage

This material is provided by KANGMA for research, laboratory or further evaluation purposes. RESEARCH USE ONLY & NOT FOR HUMAN USE.

Application Example

Remove the genomic DNA from sample.

1.Prepare the following reaction mixture in a microcentrifuge tube.

  • Total RNA 20 - 50 μg
  • 10X DNase I Buffer 5 μL
  • Recombinant DNase I 2 μL(10 U)
  • RNase Inhibitor 20 U
  • DEPC-Treated Water up to 50 μL

2.Incubate for 20 - 30 min at 37 ℃.
3.Dissolve the precipitate in a suitable amount of DEPC-treated water. Confirm the genomic DNA is removed completely by agarose electrophoresis and measure the RNA concentration. When the genomic DNA is not removed completely, increase the amount of enzyme, or extend reaction time.

Compare the digestion activity of different dilution of DNase I from D2P or other vendor. Both of them can digest 1 μg pUC19 plasmid completely in 37 ℃ for 5 min.
