After adapter ligation fragments of 250C350 bp (insert plus adaptor sequences) were isolated from an agarose gel and were PCR amplified with Illumina primers for 15 cycles. The purified DNA was captured on an Illumina flow cell for cluster generation. These libraries were submitted to high-throughput sequencing around the Illumina Genome Analyzer II (GAII).
