The RNA UltraSense™ One-Step Quantitative RT-PCR System is specially designed for amplification and real-time quantification of ultra-low abundance transcripts and RNA viruses. The optimized, ultra-concentrated system combines SuperScript™ III RT and Platinum™ Taq DNA Polymerase to provide greater priming specificity, higher product yields, and detection over a broad dynamic range. The high concentration formulation provides great flexibility with low concentration / high volume RNA samples, and improves performance with targets rich in secondary structure. As little as 25 pg/μl total RNA can be detected with a PCR efficiency of 97% (Figure 1). The RNA UltraSense™ System features:

• SuperScript™ III RT for higher temperature cDNA synthesis (up to 60°C) for greater success with RNA secondary structure
• Platinum™ Taq DNA Polymerase with hot-start technology for improved specificity
• Optimized performance with either LUX™ Fluorogenic Primers or dual-labeled fluorogenic probes
• Proprietary, ultra-concentrated buffer for addition of large sample volumes (up to 70%) and success with RNA secondary structure
• Validated performance on multiple real-time instrument platforms
• One-step format for speed, convenience, and less reaction-to-reaction variability

Applications:
Real-time quantitative amplification of RNA, including:
• RNA viruses
• Low-abundance RNA transcripts
• Difficult-to-amplify RNA targets
• High-value RNA detection and research
For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

What can I do to improve the sensitivity of my qPCR assay?

If you are targeting a low-abundance gene, you may have trouble getting Ct values in a good, reliable range (Ct > 32). To increase the sensitivity of the assay, you may want to consider the following:

- Increase the amount of RNA input into your reverse transcription reaction, if possible
- Increase the amount of cDNA in your qPCR reaction (20% by volume max)
- Try a different reverse transcription kit, such as our SuperScript VILO Master Mix, for the highest cDNA yield possible
- Consider trying a one-step or Cells-to-CT type workflow (depending on your sample type)

How do I set the baseline for my qPCR experiment?

Most times your instrument software can automatically set a proper baseline for your data. Check out our short video, Understanding Baselines, for more information on how to set them (https://www.youtube.com/watch?feature=player_embedded&v=5BjFAJHW-bE).

How do I set the threshold for my qPCR experiment?

In most cases your instrument software can automatically set a proper threshold for your data. Check out our short video, Understanding Thresholds, for more information on how to set them (https://www.youtube.com/watch?feature=player_embedded&v=H_xsuRQIM9M).

I am not getting any amplification with my TaqMan Assay or SYBR Green primer set. What is causing this?

There could be several reasons for no amplification from an assay or primer set. Please see these examples and suggested solutions in our Real-Time Troubleshooting Tool (https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/qpcr-education/real-time-pcr-troubleshooting-tool/gene-expression-quantitation-troubleshooting/no-amplification.html) for more details.

I am getting amplification in my no-template control (NTC) wells in my qPCR experiment. What is causing this?

There could be several reasons for amplification in a NTC well. Please see these examples and suggested solutions in our Real-Time Troubleshooting Tool (https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/qpcr-education/real-time-pcr-troubleshooting-tool/gene-expression-quantitation-troubleshooting/amplification-no-template-control.html) for more details.
