图6 血浆中cfRNA提取效率对比 Note： A. Schematic comparison of cfRNA extraction methods using column-based and magnetic bead-based techniques. Samples 34-1 and 35-1 represent the first 30 μL elutions, while samples 34-2 and 35-2 represent the second 20 μL elutions. B. Comparison of cfDNA copy number (per microliter of plasma) extracted from the blood plasma of two normal individuals using Kit E and Kit F. The line chart shows that the column-based method is more efficient in extraction. C. Comparison of the log copy numbers of cfRNA extracted using Kit E and Kit F from 1 mL of blood plasma from two normal individuals, with two elutions of DNA content.
