Ed specificity. Such applications include ChIPseq from restricted biological material (eg, forensic, ancient, or biopsy samples) or where the study is limited to identified enrichment web sites, for that reason the presence of false peaks is indifferent (eg, comparing the enrichment levels quantitatively in samples of cancer sufferers, employing only chosen, verified enrichment websites over oncogenic regions). However, we would caution against working with iterative fragmentation in research for which specificity is much more vital than sensitivity, as an example, de novo peak discovery, identification with the exact place of binding web pages, or biomarker research. For such applications, other solutions including the aforementioned ChIP-exo are a lot more suitable.Bioinformatics and Biology insights 2016:Laczik et alThe advantage in the iterative refragmentation technique is also indisputable in cases exactly where longer fragments have a tendency to carry the regions of interest, for example, in studies of heterochromatin or genomes with incredibly high GC content, that are much more resistant to physical fracturing.conclusionThe effects of iterative fragmentation are usually not universal; they’re largely application dependent: no matter whether it’s valuable or detrimental (or possibly neutral) is determined by the histone mark in query and also the objectives on the study.

Alternatively, we would caution against using iterative fragmentation in studies for which specificity is much more crucial than sensitivity, as an example, de novo peak discovery, identification from the precise location of binding web pages, or biomarker analysis.
