Technology
The GTC offers Next-Generation sequencing on the Illumina platform. We have two GAII systems and one HiSeq2000. The GAII systems typically yield 10-30 million reads per lane in single read or paired end mode. The HiSeq2000 typically yields 70-100 million reads per lane for only about 50% higher costs. Further costs savings can be realized with sample multiplexing.
We offer full service sample processing including library prep service with the SPRIworks system from Beckman.

Sample Submission Guidelines
Please use our sample submission forms found here. Internal users should use the online form, external users should download the excel form.
Users may submit fully prepared libraries with Illumina adapters or dsDNA for our library prep service.
User prepared libraries should be gel-purified and provided UNDILUTED in EB. Please submit 5uL of undiluted sample. We will determine the concentration by RT-PCR and make the appropriate dilutions. Excess sample will be retained in our freezers for potential future re-run. Users are also strongly encouraged to retain a portion of their samples in case of emergency.
For the library prep service please submit dsDNA (RNA samples will need to be reverse transcribed first). We will provide all reagents for adapter ligation and enrichment. There is a wide range of suitable volumes and concentrations but we will need to know approximate values.
GTC will provide sequencing primers for libraries prepared with standard Illumina adapters. If custom sequencing primers are required they must be provided at the time of sample submission.
Data
Images acquired from the sequencer are processed through the bundled Illumina image extraction pipeline to get the sequence and quality score for each base. The data is aligned to a reference genome, if requested, using an ELAND algorithm. An in-depth QC report is included in the package.

Turnaround Time
Each sequencer processes 8 samples per run, or 7 samples plus a control. Full flowcells can be run usually within two weeks of submission. Partial submissions of less than eight samples (or 7 with control) are put into a project queue, where they join existing samples or await others before processing. Wait times for partial submissions vary but are generally two weeks or less, depending on demand from other users.
Applications
Next-Generation Sequencing can be used for a wide variety of applications including ChIP-Seq, RNA-Seq, smallRNA-seq, GWAS and much more. Visit Illumina's web site or contact us to discuss your project goals.
