Overview

• Convenient optimized on-column DNase treatment using Norgen’s RNA Purification Kits
• Also includes protocol for digestion in-solution followed by RNA Clean-Up
• Guaranteed RNase-Free
• Includes Enzyme Incubation Buffer
• Cat. 25710 contains one vial of 1,600 units and Cat. 25720 contains 4 vials (1,600 units/vial)

Norgen’s RNA purification kits isolate total RNA with minimal amounts of genomic DNA contamination. However, for some sensitive downstream applications, it may be desirable to remove all traces of residual DNA. Norgen’s RNase-free DNAse I Kit, with Enzyme Incubation Buffer, can be used for optional on-column DNase digestion with any of Norgen’s RNA purification kits. Alternatively, after isolating total RNA using one of Norgen’s RNA purification kits, the RNA elution can be treated with this DNase I. The RNA can then be purified from the DNase using Norgen’s RNA Clean-Up and Concentration Kit (Cat# 23600), and the RNA can then be used in downstream applications.

Details

Each RNase-Free DNase I Kit is supplied complete with sufficient enzyme and enzyme incubation buffer for 50 or 200 reactions.

Storage Conditions
The DNase I provided is in lyophilized form. It is stable for at least 3 months if stored at room temperature. However, it is recommended to store the DNase I vial at 2 – 8ºC (or below) upon receipt to maintain stability beyond 3 months. Buffer DR and Enzyme Incubation Buffer can be stored at room temperature. After reconstitution with Buffer DR (see product manual), the DNase I should be stored at -20ºC. All reagents should remain stable for at least 1 year in their unopened containers at the appropriate storage temperature.

Introduction

This product is suitable for rapid extraction of DNA from FFPE sample. This kit uses two combination methods. High-salt Bind is conducive to remove pigments or polysaccharides from complex FFPE samples, so as to improve the purity of nucleic acid and avoid blocking aligent 2100. Alcohol mediated adsorption is conducive to improve the nucleic acid yield of high-yield samples.

Principle

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by Elution Buffer.

Advantages

• High yield – most optimal process, recovery up to 90%
• Economy – less than 50% of the price of Qiagen and other imported products
• High purity – OD 260/280 : 1.7-1.9, OD 260/230 : 1.5-2.0

Storage and Stability

Proteinase K, RNase A and MagPure Particles N should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
