Ed specificity. Such applications involve ChIPseq from limited biological material (eg, forensic, ancient, or biopsy samples) or exactly where the study is limited to known enrichment websites, as a result the presence of false peaks is indifferent (eg, comparing the enrichment levels quantitatively in samples of cancer patients, employing only chosen, verified enrichment sites over oncogenic regions). However, we would caution against employing iterative fragmentation in research for which specificity is extra crucial than sensitivity, as an example, de novo peak discovery, identification of the exact place of binding web-sites, or biomarker analysis. For such applications, other methods such as the aforementioned ChIP-exo are more appropriate.Bioinformatics and Biology insights 2016:Laczik et alThe advantage of your iterative refragmentation process is also indisputable in instances exactly where longer fragments usually carry the regions of interest, for instance, in studies of heterochromatin or genomes with extremely higher GC content, that are far more resistant to DBeQ site physical fracturing.conclusionThe effects of iterative fragmentation will not be universal; they are largely application dependent: irrespective of whether it really is advantageous or detrimental (or possibly neutral) is determined by the histone mark in query and also the objectives in the study.
