2. Figure 1
Protocol workflow. Cell-line samples were either spiked into whole blood or processed separately. Fixation was performed. After fixation, either immunomagnetic separation or prolonged storage was tested. All RNA material was checked for RNA integrity in a quality control step. Stranded RNA TruSeq libraries were prepared, sequenced, and the data analyzed. Downstream data analysis included gene expression and fusion transcript analysis.

3. Figure 2
Quality control of the integrity of RNA molecules (RIN) values for the A-549 and MCF-7 cancer cell lines. A: The graph depicts the effects of fixation and storage of of A-549 fresh and A-549 fixed at −20°C for different time periods. B: The graph depicts the effects of fixation (MCF-7 fresh and MCF-7 fixed) and epitope availability after fixation (IMS fresh and IMS fixed). FU, fluorescence units; IMS, immunomagnetic separation.

6. Figure 5
Gene expression plots with a linear fitted line. Pearson's correlation for MCF-7 cancer cell line pair (A), IMS cancer cell line pair (B), spiked blood pair (C), and A-549 cancer cell line pair (D). P < 2.2 × 10–16 in all of the sample pairs.

7. Figure 6
Relative gene expression of a selected panel of genes in spiked and unspiked blood samples. The expression measurements are based on RT-qPCR studies and demonstrate that the relative expression of CDH1, CD24, ERBB2, and KRT19 in spiked blood samples is much higher than in unspiked blood.
