  • High sensitivity and specificity
  • Simple workflow with next-day results
  • Automated data analysis using Rotor-Gene AssayManager v2.1 software

Product Details

The FGFR RGQ RT-PCR Kit is a qualitative assay for the detection of four point mutations in of the FGFR3 gene: exon 7 [p.R248C (c.742C>T), p.S249C (c.746C>G)] and exon 10 [p.G370C (c.1108G>T), p.Y373C (c.1118A>G)]. In addition, the assay detects three fusions in the FGFR3 gene (FGFR3-TACC3v1, FGFR3-TACC3v3 and FGFR3-BAIAP2L1) and two fusions in the FGFR2 gene (FGFR2-BICC1 and FGFR2-CASP7).

Principle

The FGFR RGQ RT-PCR Kit is based on the selective amplification of alterations in the FGFR2 and FGFR3 genes using the Rotor-Gene Q 5plex HRM instrument for sensitive and specific analysis. The assay exploits the qPCR oligonucleotide hydrolysis principle using TaqMan probes.

Allele-specific technology allows accurate and highly reproducible detection of alterations, based on the use of specific forward and reverse primers and probes; only a perfect match between the primers and probes with the target cDNA allows extension and amplification in the PCR reaction. Data analysis is performed automatically. Outputs for each PCR are displayed individually, with "Amplification Detected" displayed when a specific FGFR mutation is detected.

Procedure

The fast and simple workflow takes ~12 hours from Sample to Insight.

RNA is first prepared from formalin-fixed paraffin-embedded (FFPE) urothelial tumor samples using the RNeasy DSP FFPE Kit or RNeasy FFPE Kit. Purified RNA is then reverse transcribed using Reverse Transcriptase to generate cDNA for real-time PCR analysis. Optimized reverse transcription reagents and PCR master mixes provided in the kit enable high-fidelity reverse transcription and sensitive real-time PCR on the Rotor-Gene Q 5plex HRM instrument. Qualitative results are displayed in Rotor-Gene AssayManager software, informing the system operator if one or more of the four point mutations and five fusions detected by the kit are present in each sample.

Applications

The FGFR RGQ RT-PCR Kit enables qualitative detection of four point mutations and five fusions in the FGFR2 and FGFR3 genes.

FAQ ID -9030
If new dyes or chemistries appear on the real-time PCR market, will Rotor-Gene Q be capable of running those dyes?

The Rotor-Gene Q software allows creation of new excitation/detection wavelength combinations, which means that Rotor-Gene Q will work with dyes you may want to use in the future.

 

FAQ ID -2087
Do you have a protocol for Rotor-Gene software setup for the Rotor-Gene SYBR Green PCR and RT-PCR Kits?
Are there specific recommendations for performing RT-PCR on RNA isolated from paraffin-embedded samples?

Paraffin-embedded or fixed samples typically yield fragmented, partially degraded RNA. In addition, RNA quality will depend greatly on the handling of the samples before, during, and after the fixation procedure. 

If performing RT-PCR with degraded RNA, we recommend using gene-specific primers or random nonamers rather than oligo-dT primers, since the mRNA poly-A tail may have been lost due to degradation.

We recommend that the RNeasy FFPE or miRNeasy FFPE kit be used to isolate the RNA.

FAQ ID -828
What is the composition of Buffer PKD?
The exact composition of Buffer PKD is proprietary. Buffer PKD functions as a Proteinase K Digestion Buffer and is a component of, for example, the AllPrep DNA/RNA FFPE Kit, RNeasy FFPE Kit, and the miRNeasy FFPE Kit. We are sometimes asked if Buffer PKD comprises any RNase inhibitors or RNase inhibiting agents — since the formalin-fixation of the starting material has already inactivated the RNases, no such reagents are present in this buffer.
FAQ ID -2801
Which downstream applications have been tested with SARS-CoV-2-derived RNA purified from saliva collected into PAXgene Saliva Collector?

FAQ ID -627
What is the composition of Buffer RLT?

The exact composition of Buffer RLT is confidential. This buffer is a proprietary component of RNeasy Kits. Buffer RLT contains a high concentration of guanidine isothiocycanate, which supports the binding of RNA to the silica membrane. Buffer RLT can be purchased separately (cat. no. 79216)

Note: note that ß-mercaptoethanol should be added to Buffer RLT before use to effectively inactivate RNAses in the lysate (10 µl ß-Mercaptoethanol per 1 ml Buffer RLT).

FAQ ID -2793
How is the hypothesis test performed in the REST software?
In the REST 2009 software, the hypothesis test performs 10,000 random reallocations of samples and controls between the groups, and counts the number of times the relative expression on the randomly assigned group is greater than the sample data.
FAQ ID -2459
How can I check the integrity of RNA purified using RNeasy Kits?

The integrity and size distribution of total RNA purified with RNeasy Kits can be checked by denaturing-agarose gel electrophoresis, the Agilent 2100 bioanalyzer, or the QIAxcel Advanced System with the QIAxcel RNA QC Kit v2.0.

The respective ribosomal species should appear as sharp bands on the stained gel. 28S ribosomal RNA bands should be present with an intensity approximately twice that of the 18S RNA band. If the ribosomal bands are not sharp, but appear as a smear of smaller sized RNAs, it is likely that the RNA sample has suffered major degradation during preparation.

FAQ ID -2150
How many signal readings are taken during the real-time data acquisition on the Rotor-Gene Q?

At the selected data acquisition step of the thermal cycle on the Rotor-Gene Q, the fluorescent signal intensity is measured 20 times for each sample as they spin past the detector. Tubes on a rotor spin past the excitation/detection optics every 150 milliseconds. The average of the 20 readings is then taken as the fluorescence of the sample at that cycle number.

 

FAQ ID -2083
What should I do if the Rotor-Disc OTV run does not pass?

Please send the original OTV run file to QIAGEN Technical Service for further assistance.

FAQ ID -9022
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

FAQ ID - 9024
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
Is regular calibration needed with the Rotor-gene instrument?
QIAGEN recommends the annual inspection service on Rotor-gene instruments, during which all application-critical modules of the Rotor-gene are inspected and tested and an OTV check is conducted. Performed tests and test results are documented in a GMP/GLP-compliant Report. In addition, the end users can perform the temperature calibration in the lab as needed using the Rotor-Disc OTV kit.

Note: The Rotor-Disc OTV kit requires the Rotor-Disc 72 Rotor and Rotor-Disc 72 locking ring.
FAQ ID -9025
Is it possible to import a standard curve from a previous PCR run on the Rotor-Gene Q?

Yes. If the reaction efficiency between two PCR runs is not expected to vary, importing a standard curve from a previous run allows to estimate concentrations when a standard curve for the current run is not available. Curves can be imported from another channel, or from another run by clicking on 'Import Curve' in the Rotor-Gene Q software. Standard curves can be adjusted such that only the efficiency of the source curve is imported into the current run. Whether a standard curve should be adjusted depends on the PCR chemistry used. To adjust a standard curve, use a reference with a known concentration in the target run.

 

FAQ ID -2093

FAQ ID -2153
What is Tissue-Tek O.C.T., and what is it used for?

Tissue-Tek O.C.T. is an embedding compound for cryosectioning, which is soluble in water. It mainly consists of glycols and synthetic resins. Tissue-Tek O.C.T. is used as matrix for cryosectioning of tissues. Using the O.C.T. the tissue samples can be positioned more easily in the microtome and have better qualities during sectioning.

Most cryosections are fixed using non-crosslinking agents. For isolation of RNA from tissue embedded in Tissue-Tek O.C.T. using non-crosslinking agents the RNeasy Plus Micro Kit or the RNeasy Micro Kit (Protocol: Total RNA Isolation from Microdissected Cryosections), or the RNeasy Mini Kit (RNeasy Mini Protocol for the isolation of Total RNA from Animal Tissue) give great results. We strongly recommend removing as much of the embedding compound as possible prior to RNA extraction from the sections. Please see QIAGEN News article, Issue 1 1998, 'Effects of malnutrition on expression of lactase in children' for successful RNA isolation from O.C.T.-embedded tissue using the RNeasy Mini Kit.

In case crosslinking agents (e.g. formaldehyde or glyoxal-containing) were used for fixation of the tissue for cryosectioning the RNeasy FFPE Kit is the perfect choice. The RNeasy FFPE Kit is especially designed for purifying total RNA from formalin-fixed tissue sections. Special lysis and incubation conditions reverse formaldehyde modification of RNA for improved results in downstream application. The crosslinking causes the RNA to break, resulting in overall smaller molecules, which look like a smear when analyzed on a formaldehyde gel.

In case DNA as well as RNA from precious samples is of interest from the identical sections, please have a look at the AllPrep DNA/RNA Kits for unfixed tissue or the AllPrep DNA/RNA FFPE Kit for fixed tissue.

FAQ ID -530
Can I import a standard curve from a previous PCR run on the Rotor-Gene Q?

Use of endogenous control genes corrects for variation in RNA content, variation in reverse-transcription efficiency, possible RNA degradation or presence of inhibitors in the RNA sample, variation in nucleic acid recover, and differences in sample handling. The endogenous control gene ought to have consistent expression levels between samples and among treatment conditions, and ideally has a similar expression level to that of the genes of interest. Genes commonly used as references can be found at the QuantiTect Primer Assays as endogenous controls.

FAQ ID -9027
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
During data analysis, how should the threshold be set in the Yellow channel on the Rotor-Gene Q cycler to analyze the Internal Control from the QuantiFast Pathogen PCR +IC Kit or the QuantiFast Pathogen RT-PCR +IC Kit
On the Rotor-Gene Q, setting the threshold in the Yellow channel to an absolute value of 0.05 will give satisfactory results in most cases.
FAQ ID -2607
What are the effects of low A260/A230 ratios in RNA preparations on downstream applications?

The efficiency of downstream applications depends strongly on the purity of the RNA sample used.  Pure RNA should yield an A260/A230 ratio of around 2 or slightly above; however, there is no consensus on the acceptable lower limit of this ratio.  Possible candidates that can increase the A230 include “salt”, carbohydrates, peptides, and phenol (or aromatic compounds in general).  In our experience, the increased absorbance at 230 nm in RNA samples is almost always due to contamination with guanidine thiocyanate, present at very high concentrations in the lysis buffer or extraction reagent used in most RNA purification procedures.

Please find an article discussing the effect of low 260/230 ratios in RNA preparations on downstream applications on page 7 of QIAGEN Newsletter March 15, 2010 . In summary, we found that concentrations of guanidine thiocyanate of up to 100 mM in an RNA sample do not compromise the reliability of downstream applications.

 

 

FAQ ID -2248
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
How can I ensure complete genomic DNA removal when using the RNase-Free DNase Set?

To ensure efficient gDNA removal when doing an on-column digest using the RNase-Free DNase Set in combination with RNeasy Mini the following factors are crucial:

  • prevent overloading by adjusting the amount of starting material to no more than the maximum amounts recommended in the RNeasy Mini Handbook
  • ensure complete disruption and homogenization of the starting material as instructed in the section 'Disruption and homogenization of starting materials' of the handbook
  • strictly follow the protocol for on-column DNase Digestion in Appendix D of the RNeasy Mini Handbook (you can let wash buffer RW1 incubate on the column for 3-5 minutes before centrifuging to enhance removal of excess gDNA prior to applying the enzyme)

In the rare case that trace amounts of genomic DNA are still detectable in sensitive downstream applications such as e.g., realtime RT-PCR, an in-solution digest using the RNase-Free DNAase set can be performed. Instructions are presented in Appendix C of the RNeasy MinElute Cleanup Handbook.

Alternatively, a second on-column digest can be carried out in future preparations, immediately following the RW1 wash after the first incubation with DNase.

FAQ ID -1087
Does the centrifugal force have any effect on the kinetics of a PCR reaction on the Rotor-Gene Q?

No. The speed at which the samples spin on the Rotor-Gene Q is not high enough to apply any significant centrifugal force on them.

 

 

 

FAQ ID -2081
How fast does the rotor spin during a run on the Rotor-Gene Q?

The sample rotor of the Rotor-Gene Q spins continuously at a speed of 400 rpm during a run.

Can the Rotor-Gene Multiplex RT-PCR Kit be used on other cyclers?

The specific features of Rotor-Gene Kits and Rotor-Gene cyclers work synergetically to enable an ultrafast-cycling protocol. We do not guarantee that the performance of the Rotor-Gene Multiplex RT-PCR Kit with the same cycling protocol will be the same on other cyclers.

What is the composition of Buffer RPE?
The exact composition of Buffer RPE is confidential. Buffer RPE is a mild washing buffer, and a proprietary component of RNeasy Kits. Its main function is to remove traces of salts, which are still on the column due to buffers used earlier in the protocol. Ethanol, which is added by the user just before using the kit for the first time, is an important ingredient of Buffer RPE.

What is the composition of Buffer RW1?

The exact composition of Buffer RW1 is confidential. Buffer RW1 is a proprietary component of RNeasy Kits. Buffer RW1 contains a guanidine salt, as well as ethanol, and is used as a stringent washing buffer that efficiently removes biomolecules such as carbohydrates, proteins, fatty acids etc., that are non-specifically bound to the silica membrane. At the same time, RNA molecules larger than 200 bases remain bound to the column.

Note: Buffer RW1 should not be used for isolation of small RNAs, for example, microRNAs or fragmented RNA from formalin-fixed tissues, as these smaller fragments will be washed away.  Buffer RWT should be used instead.

Must I fill blank positions with empty tubes when running sample numbers lower than the rotor capacity of the Rotor Gene Q?
Yes, all empty positions in the rotor of the Rotor-Gene Q have to be filled with empty tubes. This guarantees optimal temperature repartition in the Rotor-Gene Q chamber.
