Such applications include ChIPseq from limited biological material (eg, forensic, ancient, or biopsy samples) or exactly where the study is limited to identified enrichment websites, for that reason the presence of false peaks is indifferent (eg, comparing the enrichment levels quantitatively in samples of cancer patients, making use of only selected, verified enrichment sites more than oncogenic regions). Alternatively, we would caution against applying iterative fragmentation in research for which specificity is extra critical than sensitivity, as an example, de novo peak discovery, identification on the exact location of binding web sites, or biomarker investigation. For such applications, other solutions which include the aforementioned ChIP-exo are additional appropriate.Bioinformatics and Biology insights 2016:Laczik et alThe benefit in the iterative refragmentation method can also be indisputable in situations where longer fragments are likely to carry the regions of interest, one example is, in studies of heterochromatin or genomes with very higher GC content material, that are a lot more resistant to physical fracturing.conclusionThe effects of iterative fragmentation are usually not universal; they’re largely application dependent: regardless of whether it is actually useful or detrimental (or possibly neutral) is determined by the histone mark in query along with the objectives with the study.
