Heat&Run® gDNA Removal Kit
OverView
The Heat&Run® gDNA removal kit removes contaminating gDNA from RNA prior to RT-qPCR.
The kit is based on the recombinant heat labile dsDNase, which is irreversibly inactivated at low temperatures (5 minutes at 58ºC or 15 minutes at 55ºC).
Reverse Transcription can be performed in the same tube, thereby minimizing pipetting steps and reducing hands-on time.
Protocol
The kit contains HL-dsDNase which efficiently removes gDNA from RNA preps before running RT-qPCR.
- gDNA is removed, leaving RNA ready for reverse transcription in the same tube (Figure 1).
- Heat-labile dsDNase can easily be inactivated.
- This procedure minimizes pipetting steps and reduces hands-on time.
- The Heat&Run kit is especially well suited for high throughput experiments.
The high activity of the HL-dsDNase at low temperature and its heat-lability makes it ideal to use in a combination with a heat activated RT enzyme. The contaminating genomic DNA is cleaved at ambient temperature and increasing the temperature over 50°C will inactivate the DNase and start the Reverse Transcriptase.

FAQs
The Heat&Run® kit is designed to remove contaminating genomic DNA (gDNA) from RNA samples prior to downstream applications such as RT-qPCR and NGS library preparation.
The kit contains recombinant heat-labile dsDNase (HL-dsDNase) and a 10× reaction buffer.
The Heat&Run® kit can be used before RNA sequencing when some RNA fragmentation is acceptable, such as in certain massively parallel sequencing applications.
However, the heat inactivation step may cause partial RNA degradation and is therefore not suitable for workflows that require full-length RNA integrity.
If maintaining high RNA integrity is important, consider using HL-dsDNase as a stand-alone enzyme. In this case, heat inactivation can be omitted by optimising the downstream buffer composition.
