Such applications include ChIPseq from limited biological material (eg, forensic, ancient, or biopsy samples) or exactly where the study is restricted to recognized enrichment internet sites, thus the presence of false peaks is indifferent (eg, comparing the enrichment levels quantitatively in samples of cancer individuals, working with only selected, verified enrichment web-sites over oncogenic regions). However, we would caution against using iterative fragmentation in studies for which specificity is much more critical than sensitivity, for instance, de novo peak discovery, identification with the exact place of binding web-sites, or biomarker analysis. For such applications, other solutions like the aforementioned ChIP-exo are a lot more proper.Bioinformatics and Biology insights 2016:Laczik et alThe benefit with the iterative refragmentation technique is also indisputable in circumstances exactly where longer fragments often carry the regions of interest, as an example, in research of heterochromatin or genomes with extremely higher GC content, which are a lot more resistant to physical fracturing.conclusionThe effects of iterative fragmentation usually are not universal; they’re largely application dependent: whether it’s helpful or detrimental (or possibly neutral) is determined by the histone mark in query and also the objectives from the study.
