Use of liquid biopsy dPCR assays for monitoring resistance and response

Digital PCR (dPCR) is an established method for the fast and reliable identification of significant cancer-related mutations. For liquid biopsy analysis, dPCR assays are a precise, cost-effective, and rapid method for monitoring response and resistance to treatment by testing for relevant cancer-driver and therapy-resistant mutations.

The TaqMan dPCR Liquid Biopsy assays detect and quantify the most common cancer-related mutations (e.g., EGFR, BRAF, KRAS, PIK3CA, JAK2), as well as therapy-resistant mutations (e.g., EGFR T790M). They have been verified and are guaranteed* to perform on the QuantStudio 3D Digital PCR System and other dPCR and droplet digital PCR (ddPCR) instruments, including the Bio-Rad QX-100™ and QX-200™ systems.**

Poster: TaqMan dPCR Liquid Biopsy Assays targeting the TERT promoter region

The TERT promotor region has a high incidence of mutations in multiple cancer types, yet detection of these mutations is difficult due to the high GC content and repetitive elements in this region. In this poster, learn about how we successfully designed and optimized TaqMan dPCR Liquid Biopsy Assays for TERT C228T and TERT C250T mutations with detection to 0.1%.
