Fig 7. Effect of storage temperature and time in urine samples to which Streck preservative was added.

Fig 7

The fractions were stored at 4°C, RT or 30°C for a varying storage time and supplemented with Streck preservative. Results from all included samples are shown as an average for each fraction. A: Total DNA concentrations analyzed with Qubit fluorometer. B: Total DNA concentrations analyzed with ddPCR. C: Amount of cfDNA and gDNA as determined with the FragmentAnalyzer. cfDNA = circulating cell-free DNA, ddPCR = digital droplet PCR, gDNA = genomic DNA, RT = room temperature, Streck = cfDNA Urine Preserve.
