Fragmentation is essential in most library preparation protocols for use with massively parallel sequencing systems. Complexes that generate hydroxyl radicals, such as iron-EDTA, can be used to introduce random DNA cleavage. Here we describe a chemical fragmentation method that can be incorporated into library preparation protocols for next-generation sequencing workflows. This protocol has been validated by whole genome, amplicon and exome sequencing. Chemical fragmentation is a cost-effective alternative to current fragmentation methods that has no observable sequence bias and requires no instrumentation.
