2x150bp Human Genome in Record Time with the HiSeq 2500

We are very happy to announce the BaseSpace availability of our second HiSeq 2500® dataset*. It demonstrates the ability to provide high quality 2x150bp reads in record time: 176 Gb in ~40h including on board cluster generation and sequencing, with 90.2% of bases at or above Q30, high quality alignment and variant calling.

Long reads allow a more precise analysis of gene fusions and structural variations, which have both been implicated in cancer and other diseases. Long reads also increase the quality of de novo assemblies based on metrics such as N50, contig size and genome coverage**. The incredible speed, daily throughput and data quality of the HiSeq 2500 is critical in settings where fast and accurate answers are required.

Altogether, our sample-to-analysis workflow takes around 50 hours for a 2x100bp run and around 74h for a 2x150bp run and we will soon commercialize methods to further improve this time.

Run 1 (Flow Cell 1), Run 2 (Flow Cell 2), Project (alignment and variant calling, analysis with App Store, file downloads)

Materials and Methods: Human Sample NA12878***, TruSeq Rapid SBS and Cluster Kits, PCR-free sample prep (in development), BWA/GATK analysis.
