Figure 2. Comparison of total extracted cfDNA amounts.

Figure 2

(A) cfDNA amount in ng/ml plasma per sample and extraction method. With the exception of sample P1 and sample S5, the available cfDNA concentrations for further library preparations were below 0.5 ng/µl. (B) cfDNA yields as box-and-whisker plots from the different extraction protocols. The highest yields were obtained from the Promega MaxWell protocol. While the cfDNA amounts from the Qiagen and Thermo protocols were comparable, the Stratec instrumentation yielded the lowest cfDNA amounts.
