Log2 ratio of the total number of reads in 50-kb bins from single NCI-H929 cells, shown as one cell in Panel A and a second cell in Panel B. Red bars represent copy-number gains while blue bars represent losses. The top row of the graphs in each panel depicts the control bulk sample sequenced to a depth of 90 million read pairs. The highly reproducible coverage of the PicoPLEX¢ç Gold kit enables the accurate detection of structural variants as small as 100 kb, even at shallow sequencing depths (2.5-8.5 million read pairs).
