Description

High-Purity DNase for DNA Degradation

DNase I (also referred to as DNase 1) is a versatile endonuclease that efficiently digests both single- and double-stranded DNA into oligonucleotides with 5´-phosphate and 3´-hydroxylated ends. This enzyme is essential for applications requiring precise DNA removal, ensuring high-quality RNA samples and reliable downstream results.

DNase I is widely used in RNA purification workflows, where it eliminates contaminating DNA to improve the accuracy of RNA-based applications. It is also ideal for in vitro transcription (IVT) processes and DNase I footprinting, making it a valuable tool for molecular diagnostics and mRNA synthesis.

Key Features

  • Broad Substrate Range: Efficiently degrades both ssDNA and dsDNA.
  • Optimized Activity: Performs effectively across a wide range of conditions and buffers.
  • Versatile Applications: Ideal for DNA removal in RNA prep, protein purification, and cell lysate treatments.

Applications

  • In Vitro Transcription: Ensures DNA-free RNA templates for efficient mRNA synthesis.
  • RNA Sample Preparation: Removes DNA contamination from RNA samples for high-purity results.
  • DNase I Footprinting: Maps protein-DNA interactions with precision.

Custom Options

We offer flexible customization to meet your specific needs:

  • Volume: Optimize packaging sizes to match your application scale.
  • Concentration: Customize concentrations for optimal performance.
  • Formulation: Available in liquid and lyophilized formats to suit your protocols.

Frequently Asked Questions

Why is DNase I used after in vitro transcription?

After IVT, DNase I removes the DNA template used for transcription. This ensures DNA-free RNA products for downstream applications. Learn more in our IVT guide: The Ultimate IVT Optimization and Troubleshooting Checklist.

What does "RNase-free" mean for DNase?

Most applications of DNase involve cleaning up RNA samples from DNA contaminants, such as from genomic DNA contaminants in RNA samples. Using an RNase-free DNase I helps ensure DNA contaminants are removed without compromising RNA integrity.

What is the activity of one unit of Synthego DNase I?

One unit is equal to the enzyme required to completely degrade 1 μg of pBR322 DNA in 10 minutes at 37 °C in DNase I reaction buffer.

Does DNase I degrade RNA?

No. DNase I specifically targets DNA and does not degrade RNA.
