KRAS RGQ PCR Kit

For qualitative measurement of 7 somatic mutations in the KRAS oncogene

  • Robust test that can detect low levels of mutant DNA
  • Ready-to-use system with simple workflow
  • Selective and sensitive due to ARMS and Scorpions technologies

The KRAS RGQ PCR Kit is a research use only assay for detection of 7 somatic mutations in the KRAS oncogene using real-time PCR on the the Rotor-Gene Q 5plex HRM instrument. Using Scorpions and ARMS technologies, the KRAS RGQ PCR Kit enables detection of the mutations in codons 12 and 13 of the KRAS oncogene against a background of wild-type genomic DNA.

Principle

The KRAS RGQ PCR Kit is a ready-to-use kit for the detection of 7 somatic mutations in the KRAS oncogene using real-time PCR on the Rotor-Gene Q 5plex HRM instrument. The KRAS gene encodes a protein that plays a critical role in the EGFR signaling cascade. Mutations in the KRAS gene can affect how the protein stimulates these downstream pathways. KRAS is mutated in approximately 30% of all cancer types. Cancers that exhibit a high frequency of KRAS mutation include colorectal cancer (35%) and lung (18%) cancer.

The KRAS RGQ PCR Kit utilizes two technologies — ARMS (Amplification Refractory Mutation System) and Scorpions — for detection of mutations in real-time PCR.

ARMS

Allele- or mutation-specific amplification is achieved using ARMS. Taq DNA polymerase (Taq) is effective at distinguishing between a match and a mismatch at the 3' end of a PCR primer. Specific mutated sequences are selectively amplified even in samples where the majority of the sequences do not carry the mutation. When the primer is fully matched the amplification proceeds with full efficiency. When the 3' base is mismatched, only low level background amplification occurs.

Scorpions

Detection of amplification is performed using Scorpions. Scorpions are bifunctional molecules containing a PCR primer covalently linked to a probe. The fluorophore in this probe interacts with a quencher also incorporated into the probe, that reduces fluorescence. During PCR when the probe binds to the amplicon, the fluorophore and quencher become separated. This leads to an increase in fluorescence from the reaction tube.

Procedure

The KRAS RGQ PCR Kit comprises a two-step procedure. In the first step, the control assay is performed to assess the total DNA in a sample. In the second step, both the mutation and control assays are performed to determine the presence or absence of mutated DNA.

Applications

The KRAS RGQ PCR Kit is intended for the detection of 7 somatic mutations in the KRAS oncogene and will provide a qualitative assessment of mutation status.
