To aid in the identification of patients eligible for treatment and to monitor response to therapy, DiaCarta offers QClamp® PIK3CA Mutation Detection Test in plasma and Formalin-Fixed Paraffin-Embedded (FFPE) samples which can lead to improved outcomes in cancer patients. The QClamp® PIK3CA Mutation Detection Test is an in vitro diagnostic real-time qualitative PCR assay for the detection of somatic mutations in and near codons 542 and 545 in Exon 9 and codon 1047 in Exon 20 in the human PIK3CA gene, using purified DNA extracted from FFPE or plasma.
Powered by XNA technology, the QClamp® PIK3CA Mutation Detection Test has achieved a much higher analytical sensitivity compared to other commercial qPCR kits and other cancer gene mutation detection methods. QClamp® PIK3CA Mutation Detection Test is able to detect reliably 0.1% to 0.5% mutant DNA out of wild-type DNA for targeted mutations, providing lower detection limit compared with competition due to a strict enrichment of mutant sequences while suppressing amplification of wild-type sequences.
QClamp® PIK3CA Mutation Detection Test is CE/IVD-certified.

PIK3CA Mutation and Cancer
PIK3CA (Phosphoinositide 3-kinases or PI3-Kinases) are family of lipid kinases capable of phosphorylating the 3’ position hydroxyl group of the inositol ring of phosphatidylinositol. They are involved in regulating cell growth, proliferation. Activating mutations in PIK3CA catalytic domain of the p110alpha subunit (PIK3CA) have been found at 25~40 % frequency in various types of
Not occurred frequently in lung cancers, PIK3CA mutations in lung cancer can identify groups with prognostic relevance. Because activation of PI 3 kinase pathway can come from mutations of upstream regulators, such as receptor tyrosine kinases, PTEN and RAS proteins, or even mutations in the kinase itself, effective therapeutic agent against PI 3 kinase has been very challenging.
Streamlined Workflow for QClamp® PIK3CA Mutation Detection Tests
Step 1: DNA Isolation & Quantification
Extract DNA from FFPE or plasma using a commercial DNA extraction kit followed by measuring the concentration using fluorometric analysis
Step 2: set up qpcr
Mix the assay reagents, load into PCR plate, add controls and extracted DNA ~ 30-60 minutes
Step 3: Amplification parameters
Enter amplification parameters on
qPCR instrument, load PCR plate
and start the run ~ 2.5 hours
Step 4: Data analysis
Determine the presence or absence
of mutations according to the Cq
value cutoffs ~ 15 minutes
