High-Throughput and Sensitive Quantification of Circulating Tumor DNA by Microfluidic-Based Multiplex PCR and Next-Generation Sequencing
Circulating tumor DNA (ctDNA) has potential to serve as a biomarker for noninvasive monitoring of treatment response and disease progression. However, broad clinical applicability of ctDNA has been limited by the low sensitivity, throughput and patient coverage offered by existing ctDNA detection methods. Here we report the adaptation and characterization of the MMP-Seq technology for high-throughput and sensitive quantitation of ctDNA. A multiplex PCR preamplification (PreAmp) step was developed and incorporated into the MMP-seq workflow to enable low input ctDNA analysis with enhanced sensitivity.
