ChIP-seq tags from an immunoprecipitation with antibody for H3K4 and an IGG control. The graph shows the total number of tag start positions mapped to each basepair within 1000 bp flanking all annotated RefSeq TSS. Tags mapped to the forward strand are shown in blue and the reverse strand in green. The graph also shows a very clear nucleosome depleted region located exactly at the TSS.
