Technical Information


We provide services for high-throughput next-generation sequencing using the Illumina HiSeq 2500 platform. Standard services include: Whole Exome Sequencing (WES), Whole Genome Sequencing (WGS), targeted sequencing, Transcriptome and digital expression profiling (RNA-SEQ), Gene regulation & epigenetic analysis (ChIP-SEQ), Small RNA discovery (smRNA-SEQ), and Multiplex sequencing (multiple samples in one lane).

Pricing for HiSeq 2500 sequencing is based on the length of the sequencing run, data requirement, and whether it is a single read, paired end or multiplex. The current charges for using these services are listed on the Genomics Services Price List.

Sample Submission

Customers should submit ≥6 micrograms of DNA sample at a minimum concentration of 30 ng/microliter for Whole Genome Sequencing, Whole Exome Sequencing and Target Region Sequencing. Customers should submit ≥2 micrograms of total RNA sample at a minimum concentration of 60 ng/microliter for Transcriptome and RNA-Seq.


NGS data processing and analysis are performed using BGI's proprietary pipeline. All of the sequencing data are transferred via FTP or copied to a hard drive as customer requested. There are two reports for a sequencing project, the first is the sample QC report and the second is the sequencing results. Please see Genomics Services Standard Report.

Turnaround Time

This will vary depending on the number of sample and type of sequencing. Typically, the standard turnaround time for WES and WGS is targeted to 6-8 weeks.
