QClamp® PIK3CA Mutation Detection Tests

Improved Sensitivity for Single Gene Mutation Detection

CE/IVD MARKED (OUTSIDE OF THE US) AND RESEARCH USE ONLY (IN THE US)

The QClamp® PIK3CA Mutation Detection Test for plasma sample aids in the identification of cancer patients eligible for treatment and in monitoring response to therapy, which can lead to improved outcomes in cancer patients. The QClamp® PIK3CA Mutation Detection Test is an in vitro diagnostic real-time quantitative 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 to similar assays available in the market due to robust enrichment of mutant sequences while suppressing amplification of wild-type sequences.

PIK3CA Mutation and Cancer

PIK3CA Introduction

PIK3CA (Phosphoinositide 3-kinases or PI3-Kinases) are a 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 and proliferation. Activating mutations in PIK3CA catalytic domain of the p110alpha subunit (PIK3CA) have been found at 25~40 % frequency in various types of tumors, including in colorectal cancer, breast and endometrial cancers, and other cancers, and are associated with poor prognosis. About 80 % of the point mutations reside in exon 9 and exon 20 and have been associated with resistance to cetuximab therapy in patients with colorectal cancer.

PIK3CA Mutations

Though not occurring frequently in lung cancers, PIK3CA mutations in lung cancer can be used to identify groups with prognostic relevance. Because activation of PI 3 kinase pathway can arise from mutations of upstream regulators, such as receptor tyrosine kinases, PTEN and RAS proteins, or even from mutations in the kinase itself, finding an effective therapeutic agent against PI 3 kinase has been very challenging.

Streamlined Workflow for QClamp® Gene Mutation Detection Tests

Step 1: DNA Isolation & Quantification

Extract DNA from FFPE or plasma using a commercial DNA extraction kit and measure 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
