More Information

PCRBIO 1-Step Go RT-PCR Kit is a convenient, easy-to-use kit for fast and efficient cDNA synthesis and PCR in a single tube. The redesigned buffer system and modified reverse transcriptase offer enhanced yields and increased sensitivity compared to our original 1-step RT-PCR kit.

The kit combines our modified thermostable reverse transcriptase (RTase Go) with an advanced RNase inhibitor to enhance cDNA synthesis speed and yield. The PCR step is powered by PCRBIO HS Taq DNA Polymerase giving robust RT-PCR performance with minimal or no optimisation required. Our antibody-mediated hot start technology prevents the formation of primer dimers and non-specific amplification giving improved reaction sensitivity and specificity compared to other methods.

PCRBIO 1-Step Go RT-PCR Kit can be used with any RNA template including mRNA, total RNA and viral RNA sequences and gives reliable detection of even the most challenging targets.

Applications

  • Gene expression analysis
  • Transcription analysis
  • Gene cloning
  • Multiplex RT-PCR

FAQs

Can I alter the activation time for the hot-start DNA polymerase?

We recommend using a minimum of 2 minutes for activating the polymerase. Longer times of up to 15 minutes can also be used with no detrimental effects to the enzyme.

Do I need 1-step or 2-step reaction?

1-step

Both the cDNA synthesis and PCR reactions occur in the same mix. This option is suited for high throughput applications due to its speed and ease of set up. There is also a reduced risk of contamination. It is not ideal for low quality RNA samples or if the cDNA is required for archive or separate analysis.

2-step

The cDNA synthesis and PCR reactions occur separately. This option is better suited if the cDNA product needs to be retained for analysis. It also allows for higher levels of reaction optimization. It permits control over the type and concentration of enzyme, RNA input and concentration of cDNA which, in turn, results in higher sensitivity compared to the 1-step format.

Do I need to use an RNase inhibitor in my RT reaction?

No, the RTase Go contains an RNase inhibitor to prevent any degradation and increase sensitivity.

General troubleshooting for low product/late Ct values:

If you are observing unusually late Ct values, try diluting the template RNA. By doing this, you are diluting any inhibitors which may be present to a concentration where they do not inhibit the reaction. Additionally, try increasing the reverse transcription step to 55 °C and increasing the annealing/extension temperatures. This may help resolve difficulties caused by secondary structures present in the RNA template and/or primers.

In cases where reaction inhibition may be involved, try reducing the amount of template1 or add 0.4 – 4.4 mg/ml BSA to the reaction2.

Is mRNA isolation necessary for sensitive RT-PCR?

mRNA isolation is not normally required. PCRBIO 1-Step Go RT-PCR Kit has been developed to work on samples containing as little as 1 pg total RNA or 0.01 pg mRNA.

If you’re working with rare mRNA species, use a sequence-specific primer in the RT reaction to increase the sensitivity.

What priming method can I use?

Gene specific primers can be used in the 1-step reaction.

What size amplicons can I amplify?

PCRBIO 1-step Go RT-PCR Kit has been developed to amplify amplicons up to 3 kb in size from eukaryotic DNA.

What’s the difference between PCRBIO 1-Step Go RT-PCR Kit, qPCRBIO Probe 1-Step Go and qPCRBIO SyGreen 1-Step Detect|Go Kits?

The PCRBIO 1-step Go RT-PCR Kit has been developed for endpoint RT-PCR. The qPCRBIO Probe 1-Step Go and qPCRBIO SyGreen 1-Step Detect|Go are our probe- and dye-based options for real-time RT-PCR, respectively.

Will this work for micro RNA templates?

Yes, PCRBIO 1-Step Go RT-PCR Kit can be used for micro RNA templates. Although we do no sell dedicated kits, all of our RTases can be used for miRNA quantification and analysis.

We advise that you use one of the two following approaches:

  • Use universal RT primers and add poly(A) or poly(U) tails (e.g. by poly(U)-polymerase), followed by cDNA synthesis using universal primers1,2.
  • Use specific RT primers and omit the tailing step1,3-5.

If you are unfamiliar with the specifics of those approaches, please refer to the reference list below, which serve as a guideline.
