Quality Controls & Reference Materials for Oncology Assays
CD Genomics Oncology Nucleic Acid Quality Controls & Reference Products are dedicated to supporting the promise of precision oncology by enabling the analysis of operationally challenging genomic variations within patient samples. These patient-relevant reference materials facilitate the development, validation, and implementation of next-generation sequencing (NGS) and PCR-based assays for cancer research, therapeutic monitoring, and patient stratification.
Introduction
The execution of tumor analysis assays, whether based on NGS or PCR, is often hindered by the lack of reference samples that encompass the necessary breadth of relevant genomic alterations and similarity to patient specimens. CD Genomics oncology analysis reference and QC materials are highly multiplexed and rigorously validated, including ddPCR, combining well-characterized normal or tumor cell lines with engineered biological variants. They meet the demands of targeted DNA and RNA sequencing analysis, providing high-quality QC products for various sample types, including liquid biopsies (cancer ctDNA) and FFPE samples. Our goal is to expedite the clinical application of NGS and PCR technologies in diagnosis, treatment, and management across various cancer types.
