Ultra-Sensitive on Liquid Biopsy & FFPE

QClamp® KRAS Mutation Test

Stay in control of your patient’s KRAS mutational status with confidence throughout their treatment period. The QClamp® KRAS Codon Specific Mutation Test in Codons 12, 13, 59, 61, 117, & 146 is an in vitro diagnostic real-time qualitative PCR assay for the detection of somatic mutations in and near Codons 12 and 13 in Exon 2, Codons 59 and 61 in Exon 3, and Codons 117 and 146 in Exon 4 in the human KRAS gene, using purified DNA extracted from FFPE (formalin fixed paraffin embedded), plasma, cells or tissue. The kit identifies the presence or absence of mutations in the targeted regions but does not specify the exact nature of the mutation.


• Sample Ready: Suitable for plasma and FFPE samples
• Ultra-Sensitive: Detects reliably below 1% mutant DNA by real-time PCR
• Rapid: Streamlined workflow with less than 4 hours turnaround time
• Versatile: Works with most PCR machines
• Reproducible: Robust XNA-PCR technology minimizing variability
