Extraction of urinary cell-free DNA by using triamine-modified silica particles for liquid biopsy
The presence of approximately 200-bp cell-free DNA (cfDNA) in the urine has attracted attention as a biomarker for liquid biopsy. However, it is currently useful only for diagnoses of cancers in which a large ...
