DNase-Seq

DNase-Seq (DNase I hypersensitive sites sequencing) is a method in molecular biology used to identify the location of regulatory regions, based on the genome-wide sequencing of regions super sensitive to cleavage by DNase I.[1][2] FAIRE-Seq is a successor of DNase-Seq for the genome-wide identification of accessible DNA regions in the genome. Both the protocols for determining open chromatin region have their own bias depending on underlying nucleosome structure. Such as FAIRE-seq provides higher tag-count at non-promoter regions.[3] On the other hand, Dnase-seq signal is higher at promoter regions, however DNase-seq has been shown to have better sensitivity than FAIRE-seq even at non-promoter regions.[3]
