DNase I (RNase-Free)
| Cat. No. | E091 | ||||||
| Name | DNase I (RNase-Free) | ||||||
| Unit | 200 U (100 μl) | ||||||
| Category | Molecular Biology Enzymes and Kits | ||||||
| Description |
DNase I is a non-specific endonuclease derived from bovine pancreas that catalyzes the cleavage of phosphodiester bonds in single/double-stranded DNA, chromatin, and RNA:DNA hybrids to generate di-and/or oligonucleotide (5’-phosphorylated and 3’-hydroxylated) end-products. This product is RNase-free and can be used in RNA applications.

| Application |
• Removes DNA from protein preparations and RNA samples |
||||||
| Concentration | 2 U/μl | ||||||
| Note |
One unit is defined as the amount of DNase I that catalyzes the degradation of 1 μg of DNA in 10 minutes at 37 °C into tetranucleotides or smaller fragments. Caution: Not for diagnostic use. |

| How should DNase I be stored? | |
|
DNase I should be stored at -20°C. To avoid repeated freeze-thaw cycles, it is recommended to aliquot the enzyme before freezing.
|
| Can DNase I be used for RNA purification? | |
|
Yes, DNase I (RNase-Free) is designed for RNA applications and can be used to remove genomic DNA contamination from RNA samples.
|
| How long should I incubate my sample with DNase I? | |
|
The digestion should not exceed 15 minutes to prevent RNA degradation.
|
| How do I stop the DNase I reaction? | |
|
To inactivate DNase I activity, add 1 μl of 1M EDTA (not included) and incubate at room temperature for at least 10 minutes.
|
| How much DNase I should I use per reaction? | |
|
Typically, 1 unit of DNase I is sufficient to degrade 1 µg of DNA in 10 minutes at 37°C. Adjust enzyme concentration based on the DNA amount and reaction conditions.
