The RNA-seq data in this investigation were used as an independent means to determine other cell contamination in the neutrophil and lymphocyte preparations. Only data from the neutrophils are shown. An EPIC analysis was performed to estimate the proportion of immune and cancer cells in bulk gene expression data. This analysis yielded the percentage of neutrophils, monocytes, B cells, CD4 T cells, CD8 T cells, natural killer (NK) cells, and other cells in the neutrophil preparation.
