Preparing DNA libraries for multiplexed paired-end deep sequencing for Illumina GA sequencers.

Whole-genome sequencing, also known as deep sequencing, is becoming a more affordable and efficient way to identify SNP mutations, deletions, and insertions in DNA sequences across several different strains. Two major obstacles preventing the widespread use of deep sequencers are the costs involved in services used to prepare DNA libraries for sequencing and the overall accuracy of the sequencing data. This unit describes the preparation of DNA libraries for multiplexed paired-end sequencing using the Illumina GA series sequencer. Self-preparation of DNA libraries can help reduce overall expenses, especially if optimization is required for the different samples, and use of the Illumina GA Sequencer can improve the quality of the data.
