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.

Highlights

• 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

Applications

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.
