WebNov 23, 2024 · Circulating cell-free DNA (cfDNA) in peripheral blood provides a promising opportunity to non-invasively monitor the genomes from these inaccessible tissues. WebJun 1, 2024 · Two primer pairs were designed to target the most conserved region of different human LINE elements, 13 yielding amplicons of 66 and 330 bp. As most cfDNA is approximately 170 bp in length, the 330-bp amplicon is expected to efficiently amplify contaminating HMW gDNA but not cfDNA (Figure 1 A).A real-time quantitative (q)PCR …
