Illumina DNA PCR-Free Prep is now available. This library prep kit achieves commensurate performance with TruSeq DNA PCR-Free, while reducing turnaround time and hands-on time.
TruSeq DNA PCR-Free provides simple, all-inclusive library preparation for whole-genome sequencing applications. Researchers can sequence a wide variety of organisms, from small genomes such as bacteria to human whole genomes. The workflows offer:
TruSeq DNA PCR-Free offers superior coverage of areas that are traditionally difficult to sequence, such as GC-rich regions, promoters, and repetitive content.
The workflows are tunable to a variety of read lengths and are supported on all Illumina sequencing instruments. This permits the researcher to tailor each run to the needs of the experiment.
PCR-free means reduced library bias and gaps. The result is high data quality and optimal variant detection across the genome. Excellent genome coverage quality means your results have few gaps and good coverage of GC-rich regions.
Removing PCR saves time and removes genomic coverage bias associated with PCR steps. Bead-based size selection shortens the workflow. In tandem with Illumina sequencing systems, TruSeq DNA PCR-Free provides a range of enhancements to a widely adopted library preparation workflow.
Prepare libraries for Illumina sequencing in less than a day. Illumina Qualified Methods are available on a range of automation platforms through our partners.
