Detailní popis

Thermo Scientific RapidOut DNA Removal Kit rapidly and safely removes genomic DNA from total RNA and mRNA preparations. Complete digestion of DNA and safe removal of DNase I from the digestion reaction is ensured without RNA damaging steps, such as heating or organic extraction. First, the RNA sample is treated with recombinant RNase-free DNase I to levels below the limit of detection by routine PCR. DNase I is safely removed subsequently using proprietary DNase Removal Reagent (DRR).

DRR efficiently binds DNase I and the complex is collected at the bottom of the tube by centrifugation. The purified RNA is collected as a supernatant. The RNA after RapidOut procedure is free from DNA contamination and free of DNase I. It is ready to use in different applications including end-point or real-time RT-PCR, cloning, microarrays, and Northern blotting.


  • Efficient – complete ds and ssDNA digestion and proprietary technology for DNase I removal
  • Rapid – single step sufficient for complete DNase I removal
  • Safe – no need for toxic organic extractions or RNA-damaging heating steps


Main Applications

  • RNA isolation and RNA analysis, particularly RT-qPCR and RT-PCR (customers performing expression analysis of low transcription level genes.
  • Customers performing ds-cDNA synthesis from total RNA preps.

Other applications

  • Elimination of DNA from RNA for microinjections and transfection.
  • Elimination of DNA from RNA prior microarray analysis.
  • Elimination of DNA from RNA prior Northern blot analysis.


Component Amount
DNase I, RNase-free (1 U/µL) 250 µL
10X Reaction Buffer with MgCl2 1 mL
DNase Removal Reagent (DRR) 500 µL
Water, nuclease-free 2 × 1.25 mL
Hazardous No
Quality Control Ribonuclease Assay
For DRR:
No contaminating RNase was detected after incubation of 10 µL of DRR with 160 ng of 2 kb RNA transcript for 4 hours at 37°C.
For DNase I:
No contaminating RNase was detected after incubation of 5u of DNase I with 160 ng of 2kb RNA transcript for 4 hours at 37°C.

DNase I removal efficiency
RNA sample after RapidOut procedure was incubated with 1 µg of supercoiled plasmid DNA for 15 min at 37°C. Less than 20% of supercoil DNA was transformed to nicked and linear forms.

Functional testing
Of the kit:
DRR is functionally tested in RT-qPCR amplification reaction with RNA treated with RapidOut DNA Removal Kit.
Of DNase I:
DNase I is functionally tested in a unit activity assay: one unit of the enzyme completely degrades 1 µg of pUC19 DNA in 10 min at 37°C.
Storage Condition -20 C
