Ed specificity. Such applications consist of ChIPseq from restricted biological material (eg, forensic, ancient, or biopsy samples) or where the study is limited to recognized enrichment web sites, for that reason the presence of false peaks is indifferent (eg, comparing the enrichment levels quantitatively in samples of cancer individuals, applying only selected, verified enrichment web pages more than oncogenic regions). However, we would caution against making use of iterative fragmentation in research for which specificity is much more crucial than sensitivity, by way of example, de novo peak discovery, identification on the exact place of binding sites, or biomarker research. For such applications, other approaches for instance the aforementioned ChIP-exo are extra proper.Bioinformatics and Biology insights 2016:Laczik et alThe benefit in the iterative refragmentation process is also indisputable in situations where longer fragments are inclined to carry the regions of interest, for instance, in research of heterochromatin or genomes with incredibly higher GC content material, that are extra resistant to physical fracturing.conclusionThe effects of iterative fragmentation are certainly not universal; they are largely application dependent: regardless of whether it truly is valuable or detrimental (or possibly neutral) is determined by the histone mark in query plus the objectives in the study.
