Abstract 5575: A multiplexed RE-qPCR cell-free DNA assay to assess response and resistance to cancer therapy

A qPCR multiplex that utilizes two types of multi-copy retrotransposable elements (RE) in the human genome, as target loci, has been developed and validated. The single-well, qPCR reaction amplifies 80bp, 265bp and an internal-positive-control simultaneously, within 2 hours and with high PCR efficiencies. The selected RE targets comprise over 1500 copies in the genome and allow robust detection of low level cell-free (cf) DNA pg/µL) from Citation Format: Sudhir K.
