Poster Information
Abstract: Liquid biopsy is gaining prevalence as a non-invasive alternative approach for screening of health-related issues. Samples for liquid biopsy can come from plasma, serum, urine, saliva, or cerebrospinal fluid, where small fragments of DNA and RNA have been released from cells. The most prevalent bio-markers isolated from liquid biopsy include circulating tumor cells, circulating tumor DNA, cell-free DNA (cfDNA), circulating endothelial cells, and exosomes containing RNA. Recent studies have shown that cfDNA fragmentation provides information about the cause and tissue of origin through the fragmentation pattern and sequence. Quality analysis ensures successful sequencing of precious samples. Investigation of sizing, concentration, and distribution patterns from circulating DNA and RNA from plasma and serum was performed with the Agilent Femto Pulse system. An extended nucleosome pattern was observed from cfDNA isolated from human serum. Additionally, quality analysis provided reliable sizing and concentration, while providing a visual assessment of the sample.
