Example 3
1 μL of genomic DNA was processed using a NEBNext dsDNA Fragmentase kit (New England Biolabs) by following the manufacturer's protocol. Incubation time was extended to 45 minutes at 37° C. The fragmentation reaction was stopped by adding 5 μL of 0.5M EDTA pH 8.0, and was purified by adding 2× volumes of Ampure XP beads (Beckman Coulter, A63881) according to the manufacturer's protocol. Fragmented DNA was analyzed on a Bioanalyzer with a High Sensitivity DNA kit (Agilent). The size range of fragmented DNA was typically from about 100 bp to about 200 bp with a peak of about 150 bp.
