Product Details

The PIK3CA RGQ PCR Kit is a real-time qualitative PCR test for the detection of 11 mutations in the phosphatidylinositol 3-kinase catalytic subunit alpha (PIK3CA) gene using a sample of DNA extracted from either formalin-fixed, paraffin-embedded (FFPE) breast tumor tissue or K2EDTA anticoagulated blood plasma, taken from a patient with breast cancer.


The PIK3CA RGQ PCR Kit is comprised of six reaction mixes; one control reaction targeting exon 15 and five mutation-specific reactions utilized to detect 11 mutations in exons 7, 9 and 20 of the PIK3CA gene (Exon 7: C420R; Exon 9: E542K; E545A, E545D [1635G>T only], E545G, E545K, Q546E, Q546R; and Exon 20: H1047L, H1047R, H1047Y). Allele-specific technology allows accurate and highly reproducible detection of mutations; DNA is selectively amplified using ARMS primers, probes and PCR clamps, with sensitive signal detection using the Rotor-Gene Q 5plex HRM instrument. Data analysis is performed automatically. Outputs for each PCR are displayed individually, with "Amplification Detected" displayed when a specific PIK3CA mutation is detected.


The simple and straightforward testing workflow begins with manual DNA extraction from either FFPE breast tumor tissue (using the QIAamp DSP DNA FFPE Tissue Kit or QIAamp DNA FFPE Tissue Kit) or from K2EDTA anticoagulated plasma (using the QIAamp DSP Circulating Nucleic Acid Kit or QIAamp Circulating Nucleic Acid Kit), followed by sensitive real-time PCR on the Rotor-Gene Q 5plex HRM instrument. Rotor-Gene AssayManager software rapidly and accurately reports results, informing the system operator if one or more of the 11 mutations detected by the kit are present in each sample. The kit is a qualitative assay that can yield results in less than two working days.

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.
