DiaCarta Inc. Launches Ultra-Sensitive TaqMan-Based qPCR Assays for Cancer Gene Mutation Detection

by | Oct 29, 2018 | Press Releases

DIACARTA Inc., a precision molecular diagnostics company headquartered in Richmond, California, today announced that it is launching a new suite of CE-IVD marked highly sensitive hydrolysis probe (TaqMan qPCR) based QClamp® assays for detection of common cancer mutations in genes, such as KRAS, NRAS, BRAF, EGFR, PIK3CA and JAK2, using tissue biopsy (FFPE) and liquid biopsy (cfDNA) samples. The tests are validated on standard real-time qPCR instruments including Thermo Fisher Scientific Quantstudio 5, Roche LightCycler® 480 and Bio-Rad CFX384. The analytical sensitivity ranges from 0.1 to 0.5% for variant allelic frequency, providing lower detection limit compared with competition due to application of DiaCarta’s proprietary XNA technology. The XNA technology selectively enriches mutant sequences while suppressing amplification of wild-type sequences, allowing identification of cancer gene mutations from small population of cells among large number of normal cells, thus making early cancer gene mutation detection possible.

High sensitivity detection of somatic cell gene mutations is not only critical for testing due to tumor tissue heterogeneity but also important for guidance in targeted therapy and monitoring of disease recurrence. DiaCarta’s highly innovative QClamp® TaqMan gene mutation tests are configured to work with DNA extracted from traditional formalin fixed paraffin embedded (FFPE) tumor biopsy samples as well as minimally invasive liquid biopsy plasma samples.

DiaCarta Receives CE/IVD for its New COVID 19 Test that Identifies Delta Plus and New Variants

DiaCarta Inc., a precision molecular diagnostics company and leading developer of novel oncology tests using liquid biopsy today announced that its new QuantiVirus™ SARS-CoV-2 Variant Detection Test received the CE/IVD marking and therefore, can now be commercialized within the EU and rest of the world. This new test screens for the SARS-CoV-2 virus and simultaneously identifies and differentiates all the new mutating COVID 19 variants including the Alpha (UK), Beta (S. Africa), Gamma (Brazil), Delta (India), Delta Plus (India), Epsilon (California) and the Kappa (India) variants.

DiaCarta’s Novel XNA Technology Rapidly Detects Raging New SARS-CoV-2 Variants

DiaCarta Inc., a precision molecular diagnostics company and leading developer of novel oncology tests using liquid biopsy today announced the publication of a study entitled “A Rapid SARS-CoV-2 Variant Detection by Molecular-Clamping Based RT-qPCR” in MedRxiV that demonstrates the enhanced sensitivity and specificity using its proprietary XNA based Molecular Clamping Technology that uses innovative synthetic Xenonucleic acid molecular oligomers (XNA) that hybridize with target wild-type DNA sequences, acting as molecular clamps, to enable the accurate amplification of mutant sequences only, using quantitative real-time polymerase chain reactions (qPCR).
