Sequencing depth of ChIP-seq using various antibodies in both bam testis and S2 cell samples. Sequencing depth is analyzed by calculating the enriched regions for each subsample of the corresponding ChIP-seq experiment. The blue line represents the trend line. The x-axis of the plot indicates the percentage of subsample reads compared to the total unique reads, whereas the y-axis indicates the identified islands.
