TaqMan Fast Virus 1-Step Master Mix is designed for fast, highly sensitive real-time RT-PCR even in the presence of challenging PCR inhibitors. The 4X formulation provides enhanced detection of both RNA and DNA viruses and is ideal for multiplex gene expression studies, even with low target input. The TaqMan Fast Virus 1-Step Master Mix provides a single-tube format for uniform handling and processing, while delivering qPCR cycling in less than 30 minutes, helpful when working in high throughput workflows.
Key product features:
Two formulations
The master mix is available in two formulations:
High sensitivity
Many common research samples with viral nucleic acids have very low levels of target. We have optimized the master mix for high-sensitivity detection of viral targets. The higher-concentration master mix allows you to set up smaller reactions, which means that you can perform fast cycling protocols and obtain at least the same sensitivity as is expected from standard-cycling qPCR. Alternatively, larger sample input amounts can be added to standard reaction volumes for more accurate quantification of low-titer samples (figure below).
Consistent results in the presence of inhibitors
Research samples commonly assayed for viruses include blood, dirt, and tissues. Buffer components and proprietary additives in the TaqMan Fast Virus 1-Step Master Mix have been optimized to handle RT-PCR inhibitors (figure below) to help ensure consistent performance even with these difficult samples, so that you can be more confident in your results.
Flexibility in targets
It is common for labs to test for both RNA and DNA viruses in a variety of samples. To simplify your experiments, a single TaqMan Fast Virus 1-Step Master Mix protocol has been developed to assay both types of nucleic acid, so you can perform RNA and DNA virus queries next to each other on the same plate using the same handling steps (figure below). Additionally, because virus research often includes multiplexed primers and probes and internal reaction controls, we have optimized the master mix to work with multiple target amplicons (figure below).
Fast results
The TaqMan Fast Virus 1-Step Master Mix speeds your time to results and maximizes the use of your real-time PCR instruments with a fast protocol. The high-concentration formulation allows for more target nucleic acid sample to be added in the smaller reaction volumes required to run fast protocols. This enables you to maintain sensitivity with low-titer research samples while improving speed and throughput (figure below).
TaqMan Fast Virus 1-Step Master Mix provides a reliable and efficient reagent for real-time RT-PCR of virus samples that does not sacrifice accuracy. Its robust performance in the presence of common RT-PCR inhibitors and its convenient and flexible reaction setup allows you to have more confidence in your results.
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)
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).
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).
