Titration experiment: Detection of contaminants in sRNA preparations of human plasma using different input volumes and extraction columns. a Detected levels of the six contaminant sRNA sequences in sRNA sequencing data of preparations using 0 to 1115 μL human plasma and regular or ultra-clean RNeasy spin columns. b Detailed view of the data displayed in a for 100 μL of human plasma as input to regular and ultra-clean RNeasy spin columns. Cpm counts per million. Error bars indicate one standard deviation; data points are available in Additional file 2: Table S12
