title: Paired end 68O3-3 WGS
design: 200 ng gDNA for a 550 bp insert size is fragmented by Covaris. The fragmented DNA are bluntended and phosphorylated, and end repaired. The appropriate library size was selected using different ratios of the sample purification beads. A single A is ligated to the 3 end, Illumina adapters are then ligated to the fragments.
