EGFR Multiplex cfDNA Reference Standard Set

High-throughput platforms such as PCR-based assays and Next Generation Sequencing (NGS) give laboratories much greater power when profiling cfDNA samples. However, small quantities of DNA in combination with complex variants at low allelic frequencies represents one of the major challenges users encounter when profiling cfDNA.

Horizon Discovery has developed a comprehensive cfDNA Reference Standard range to support the development and continued validation of cfDNA assays. Our cfDNA products are derived from human cell lines and fragmented to an average size of 160 bp to closely resemble cfDNA extracted from human plasma.

The EGFR Multiplex cfDNA Reference Standard is supplied at 5%, 1%, 0.1% and 0% (EGFR Multiplex wild type) allelic frequencies and covers ten EGFR variants implicated in the responsiveness to EGFR tyrosine kinase inhibitors (EGFR-TKIs) and anti-EGFR monoclonal antibodies. This product covers clinically relevant SNPs, insertions and deletions in EGFR and can be used to optimize, validate or routinely monitor assay performance.

With this product, you are able to:

• Analyze the sensitivity and specificity of your assay
• Gain certainty of the limit of detection and limit of quantification
• Optimize and validate new EGFR-specific assays and routinely monitor their performance
