The RNase-Free DNase Set (1,500 Units) provides a rapid and efficient on-column digestion of DNA during RNA purification from a wide variety of sample sources using EasyPrepTM RNA Miniprep Kits. The DNases can be efficiently removed in subsequent steps. Generally, DNase digestion is no required for RNA purified with EasyPrepTM RNA Kits since the silica-membrance, spin-column technology efficiently removes the majority of the DNA without DNase treatment. However, complete DNA removed may be necessary for certain RNA applications that are sensitive to very small of DNA. Kit includes enzyme and reaction buffer.

Specific Activity: ≥ 2000 Kunitz units/mg Form: Lyophilized Powder Storage: 4°C DNase Ⅰ (RNase-free) is an endonuclease that nonspecifically cleaves DNA to release di-, tri- and oligonucleotide products with 5´-phosphorylated and 3´-hydroxylated ends. DNase I acts on single- and double-stranded DNA, chromatin and RNA:DNA hybrids. Feature Recombinant enzyme Purified from non-animal host with a lower level of intrinsic RNases. Applications Degradation of DNA template in transcription reactions Removal of contaminating genomic DNA from RNA samples DNase I footprinting Nick Translation Quality Control The absence of ribonucleases is confirmed by appropriate quality test. Functionally tested for digestion of template DNA after in vitro transcription Source: A E. Coli strain that carries an MBP fusion clone of Bovine Pancreatic DNase I. Molecular Weight: 29 kDa monomer Definition of Activity Unit One unit of the enzyme completely degrades 1 μg of plasmid DNA in 10 min at 37°C. Enzyme activity is assayed in the following mixture: 40 mM Tris-HCl (pH 8.0), 10 mM MgSO4, 1 mM CaCl2, 1 μg of pUC19 DNA. Inhibition and Inactivation Inhibitors: metal chelators, transition metals (e.g., Zn) in millimolar concentrations, SDS (even at concentrations less than 0.1%), reducing agents (DTT and beta-mercaptoethanol), ionic strength above 50-100 mM. Inactivated by heating at 65°C for 10 min in the presence of EGTA or EDTA (use at least 1 mol of EGTA/EDTA per 1 mol of Mn2+/Mg2+). Note: DNase I is sensitive to physical denaturation. Mix gently by inverting the tube. Do not Vortex. Preparation InstructionsDNase I is soluble in 0.15 M NaCl at 5 mg/ml. Solutions of DNase I at 5 mg/ml in 0.15 M NaCl may lose 10% of its activity when stored for a week in aliquots at -20°C. The same solutions stored in aliquots at 2-8°C can lose 20% activity. Alternatively, solutions at a minimum concentration of 1 mg protein/ml, with 5 mM calcium chloride and stored at -20°C, may retain 90% activity for at least a year. Solutions containing 0.1 mg protein/ml are considerably less stable, and may require gelatin as stabilizer. For applications unaffected by glycerol, two other storage buffers are options, as these formulations do not freeze at -20°C. 20 mM sodium acetate (pH 6.5), containing 5 mM CaCl2 and 0.1 mM phenylmethylsulfonyl fluoride (PMSF), 50% (v/v) glycerol, with DNase I at 5 mg/ml. 10 mM Tris-HCl (pH 7.5), 50 mM NaCl, 10 mM MgCl2, 1 mM DTT, 50% (v/v) glycerol, with DNase I at 2 mg/ml.
