Principle

The Rotor-Gene SYBR Green PCR Kit enables rapid and reliable real-time PCR quantification on the Rotor-Gene Q without the need for optimization of reaction and cycling conditions. The fluorescent dye SYBR Green I in the master mix enables the analysis of many different targets without having to synthesize target-specific labeled probes. Highly specific amplification is assured through a balanced combination of K+ and NH4+ ions, which promote specific primer annealing, enabling high PCR specificity and sensitivity (see figure " Specific primer annealing"). Fast cycling without compromising performance is achieved using Q-Bond, a novel PCR additive that enables cycler run times of as low as 45 minutes (see figure " Fast primer annealing").

FAQ

Will QuantiTect Primer Assays work with Rotor-Gene SYBR Green Kits using an annealing step at 60ºC?

Based on our extensive and successful testing of many QuantiTect Primer Assays with Rotor-Gene SYBR Green PCR Kits, we guarantee this.

 

 

FAQ ID -2124
Do you have a protocol for Rotor-Gene software setup for the Rotor-Gene SYBR Green PCR and RT-PCR Kits?
Do you have any information or guidelines regarding the choice of reference genes for real-time PCR?

Yes, please visit our website section 'Using endogenous control genes in real-time RT-PCR' for general information. It provides a list of relative gene expression levels for commonly used human and mouse reference genes.

We offer a set of ready-to-order control genes for use in SYBR Green based as well as probe based real-time RT-PCR.

In addition, you may want to refer to the following citations on reference gene selection for quantitative real-time PCR:

FAQ ID -2371
Do the master mixes in Rotor-Gene Kits contain dUTP to allow UNG pretreatment?

No. The master mixes in Rotor-Gene Kits contain dTTP instead of dUTP. If UNG treatment is required, we recommend using QuantiTect +UNG Kits. QuantiTect Kits are also compatible with the Rotor-Gene Q; however, the kits require a significantly longer cycling time.

 

 

FAQ ID -2117
How do I create a workspace that is free of DNA contamination, prior to carrying out a qPCR experiment?

Any DNA contamination will artificially inflate the SYBR Green signal, yielding skewed gene expression profiles and false-positive signals. The most common source of DNA contamination is from PCR products generated during previous experiments. Such contamination is most often due to the improper disposal of tubes, tips, and gels that previously came into contact with PCR products. Additionally, PCR products may also contaminate pipettors, racks, work pads, and commonly used reagents such as water and buffers. To minimize the risk of contaminating your experiment with extraneous DNA, the following steps should be taken:

 

  • Remove a single aliquot of water from your PCR-grade stock, sufficient to complete the experiment. This minimizes the number of times that the stock container is opened, thereby minimizing contamination risks.
  • Use only fresh PCR-grade reagents and disposable labware.
  • Treat any labware (tubes, tips, and tip boxes) used in PCR with 10% bleach, before discarding.
  • Maintain a dedicated workspace for PCR setup (perhaps a PCR-only hood), away from areas of the lab where post-PCR work is done, such as running gels, enzyme digestions, and cloning.
  • Change the lab bench pads/papers often and decontaminate lab benches and labware (racks, pipettors, etc.) before each use by washing with 10% bleach, and/or exposing to UV light for at least 10 minutes. This serves to degrade and/or inactivate contaminating DNA.
  • Before, during, and after the experiment, minimize the opening and closing of any tubes or plates used during the experiment.  
FAQ ID -2654
What is a QuantiTect Primer Assay?

QuantiTect Primer Assays are primer pairs designed and bioinformatically validated specifically for real-time RT-PCR with SYBR Green detection. To find a primer assay for your target gene of interest, please visit our GeneGlobe data base.

For best results, we strongly recommend using QuantiTect Primer Assays in combination with QIAGEN's products for SYBR Green-based Real-Time PCR and RT-PCR.

FAQ ID -1141
Why is a 2-step (and not a 3-step) cycling protocol recommended for Rotor-Gene SYBR Green Kits?

This type of cycling allows a significant reduction in cycling time for Rotor-Gene SYBR Green PCR Kits. It is more effective than reducing the individual times for annealing and extension.

 

FAQ ID -2122
Why is the initial activation step different for Rotor-Gene Probe, SYBR Green and Multiplex Kits?

The buffer composition, which affects the initial reactivation of HotStarTaq Plus DNA Polymerase, has been optimized for each respective Rotor-Gene Kit.

 

FAQ ID -2118
What is the threshold cycle or Ct value?
The Ct or threshold cycle value is the cycle number at which the fluorescence generated within a reaction crosses the fluorescence threshold, a fluorescent signal significantly above the background fluorescence. At the threshold cycle, a detectable amount of amplicon product has been generated during the early exponential phase of the reaction. The threshold cycle is inversely proportional to the original relative expression level of the gene of interest.
FAQ ID -2682
How do you achieve fast cycling, yet still deliver the same performance in PCR as that achieved with standard cycling?

Our unique multiplex PCR buffer system with ammonium and potassium ions and Factor MP has been further optimized in QuantiFast and Rotor-Gene Kits. We have also discovered Q-Bond, a buffer component which supports the rapid formation of the polymerase–primer–template complex, leading to reduced annealing times.

FAQ ID -1430
How can I predict the percent qPCR signal due to contaminating DNA, for a given qPCR assay, and its matching NRT control?

Assuming 100% amplification efficiency, each step increase in Ct value represents a doubling in the amount of qPCR template. Therefore, evaluating the difference in Ct values between the qPCR assay, and its matching NRT control, leads to the following predictions:

CtNRT - Ct+RT Fraction of gene expression signal due to contaminating DNA Percentage of gene expression signal due to contaminating DNA
1 (1/21) = 1/2 50%
2 (1/22) = 1/4 25%
3 (1/23) = 1/8 13%
4 (1/24) = 1/16 6%
5 (1/25) = 1/32 3%

FAQ ID -2688
What real-time cycler should I use for my qPCR experiments?
There are several manufacturers of high-quality real-time cyclers. These include QIAGEN's Rotor-Gene Q, Applied Biosystems, BioRad, Stratagene, Eppendorf, Roche, TaKaRa, Fluidigm, and Cepheid. The important thing to keep in mind is that, once you select an instrument to use, you must use compatible Rotor-Gene Discs and tubes, 96 or 384 well plates, and qPCR master mixes that are optimized for use in that particular instrument.  For example, QIAGEN's Rotor-Gene SYBR Green, Probe, and Multiplex real-time master mixes.  
FAQ ID -2670
What is a dissociation curve, and why is it important to run a dissociation curve, following qPCR using SYBR Green chemistry?

Dissociation curves are carried out at the end of a PCR experiment by following a 3-step procedure.

First, all the components are denatured at 95°C, followed by complete annealing at a set temperature (based on the primer Tm values), followed by a gradual increase in temperature up to 95°C. Fluorescence intensity is monitored during this final temperature increase, resulting in the generation of a melting curve or dissociation curve.

By analyzing the first derivative of such a curve, you can readily assess the homogeneity of the PCR products, including the presence of primer–dimers, thereby determining the specificity of the PCR reaction. It is important to carry out such post-PCR analyses when using SYBR Green probe chemistry due to this reagent's lack of sequence specificity.

FAQ ID -2678
Are Rotor-Gene Kits compatible with reaction setup using the QIAgility instrument?

The majority of the Rotor-Gene Kit data shown in our literature has been generated with the help of the QIAgility instrument. We did not observe any problems during the pipetting steps.

 

FAQ ID -2116
Do QuantiTect Primer Assays also work with Rotor-Gene SYBR Green PCR Kits?

We have performed numerous tests comparing the performance of Rotor-Gene SYBR Green PCR Kits and QuantiTect Kits with QuantiTect Primer Assays. Due to the optimized ion concentrations in the PCR buffers, both perform equally well with QuantiTect Primer Assays and do not require any adjustment of primer concentration.

 

FAQ ID -2123
What are the main differences between Rotor-Gene and QuantiTect or QuantiFast PCR Kits?

Rotor-Gene Kits are specifically developed for the Rotor-Gene Q PCR Cycler. The unique rotary system of the cycler combined with the kits’ proprietary buffer system enable ultrafast cycling. Rotor-Gene Kits do not contain ROX dye since no normalization to a passive reference is required. Also, Rotor-Gene Kits do not contain dUTP; therefore, UNG pretreatment is not possible.

 

FAQ ID -2119
Will Rotor-Gene Kits also work on the Rotor-Gene 6000 and 3000 cyclers?

Yes. Rotor-Gene Kits will also work on the Rotor-Gene 6000 and Rotor-Gene 3000 PCR cyclers with the cycling conditions specified in the Rotor-Gene kit handbooks.

 

FAQ ID -2121
Why do I see multiple high-intensity peaks in my qPCR dissociation curve at temperatures less than 70 ºC?

If the extra peaks seem irregular or noisy, do not occur in all samples, and occur at temperatures less than 70 ºC, then these peaks may not represent real PCR products and instead may represent artifacts caused by instrument settings.

Usually extra peaks caused by secondary products are smooth and regular, occur reproducibly in most samples, and occur at temperatures greater than 70 ºC. Characterization of the product by agarose gel electrophoresis is the best way to distinguish between these cases. If only one band appears by agarose gel then the extra peaks in the dissociation curve are instrument artifacts and not real products. If this is the case, refer to the thermal cycler user manual, and confirm that all instrument settings (smooth factor, etc.) are set to their optimal values.
