Abstract
Different ChIP-Seq protocolsmay have a significant impact on the final outcome in terms of quality, number and distribution of called peaks. Sample DNA undergoes a long procedure before the final sequencing step, and damaged DNA can result in excessive mismatches in the alignment with reference genome. In this letter, we present the effect of well-defined modifications (timing of formaldehyde crosslink reversal, brand of the sonicator) of standard ChIP-Seq protocol on parallel samples derived from the same cell line correlating the initial DNA quality control metrics to the final bioinformatics analysis results.
