QClamp® Gene Mutation Detection Kits
QClamp® Gene Mutation Detection kits consist of SYBR-green based qPCR assay reagents that are ideal for screening rare and actionable somatic mutations in oncogenes. The assay utilizes a sequence-specific clamp (Xeno-Nucleic Acid XNA probe) that suppresses PCR amplification of wild-type DNA template and selectively amplifies only mutant template. The kits represent a rapid, reproducible and affordable solution which employs a simple workflow and PCR machines that are commonly used in research and clinical labs.
Leveraging the XNA-PCR chemistry, QClamp® is also the most reliable tool for validating next-gen sequencing (NGS) results. It is the only technology that provides detection sensitivity of 0.1% or lower, a level that cannot be achieved by droplet digital PCR and Sanger sequencing. The validation assays can be completed in two hours for a variety of specimens, including solid tumors (e.g. FFPE tissues) and liquid biopsies (e.g. circulating tumor DNA).
How it works
QClamp® is a revolutionary new way to screen for somatic mutations that utilize a sequence-specific clamp that suppresses PCR amplification of wild-type template DNA. QClamp® allows selective PCR amplification of only mutant templates, which allows the detection of mutant DNA in the presence of a large excess of wild-type templates from a variety of samples including FFPE, liquid biopsy, and traditionally challenging cytology samples.

“QClamp® XNA technology is the most sensitive and detected mutations missed by …”
“Our lab did a good comparison study for BRAF mutations with all the technologies available in the market and found that QClamp® XNA technology is the most sensitive and detected mutations missed by all current methods including NGS and ddPCR. I strongly recommend this technology!” Read More
