Sample handling errors and cross-contamination are minimized via end-to-end barcoding of plasticware along with molecular DNA barcoding of constructs. Automation-friendly magnetic bead-based size selection and cleanup steps have been devised eliminating major bottlenecks and significant sources of error. Using this methodology one technician can create 96 sequence-ready 454 libraries in 2 days a dramatic improvement over the standard method. Background The emergence of next-generation sequencing technologies such as the Roche 454 Genome Sequencer the Illumina Genome Analyzer the Applied Biosystems SOLiD sequencer and others has provided the opportunity for both large genome centers and individual labs to generate DNA sequence data at an unprecedented scale 1 . However as sequence output continues to increase dramatically processes to generate sequence-ready libraries lag behind in scale. The minimum unit of sequence data for example lane or channel already exceeds the amount required for small projects such as viral or bacterial genomes and will continue to increase. As a result projects with large numbers of samples but small sequence per sample requirements become increasingly challenging to .
