Fig. 1. Effect of different collection tube on plasma DNA concentration after RT storage.

Blood samples were drawn into Competitor S and CONSgen tube and stored at RT. Aliquots of blood were transfer at indicated times and the plasma was separated. After cfDNA isolation from plasma, cfDNA was analyzed by Bioanalyzer 2200 with High Sensitivity D1K ScreenTape.
