| Cat# |
DIA-471 |
| Description |
A nuclease that cleaves DNA phosphodiester bonds, producing 5′-phosphate and 3′-hydroxyl oligonucleotides. Highly active and heat-labile; preferentially degrades dsDNA (≥ 5000× more active on dsDNA than ssDNA) while preserving ssDNA and RNA. Inactivated irreversibly after 5 min at 55 °C. Compatible with M-MLV and AMV reaction buffers, ideal for removing genomic DNA contamination in reverse transcription reactions. |
| Unit Definition |
One unit (U) is defined as the amount of enzyme that increases the absorbance at 260 nm by 0.001 OD per minute under the assay conditions of high-molecular-weight dsDNA substrate at 25 °C and pH 5.0. |
| Storage |
–20 °C |
| Inhibitors |
Metal chelators, transition metals, SDS, and reducing agents |
| Applications |
Preparation of RNA or ssDNA samples free of dsDNA; removal of genomic DNA contamination from RNA samples; removal of DNA templates after in vitro RNA transcription. |
