Illumina sequencing-by-synthesis is the primary workhorse of the BioMicro Center. These instruments produce millions of reads simultaneously and are used in a very broad spectrum of applications.

<!-- commenting GA out 2/2/17 NK === Genome Analyzer IIx === | |||
[[Image:GAIIxcollage.jpg|right|200px]] The Genome Analyzer II (GAII) is the oldest sequencers in the BioMicro Center and remain the most flexible. The newer generations of Illumina sequencers have been designed with increasing focus on clinical applications and have removed some of the "hands on" aspects of the older GAIIs. The GAIIs remain the only sequencers where the actual images of the flowcell can be reprocessed for example. The GAII/IIx can produce 20-40m reads per lane passing filter and typically runs read lengths of 36-150nt per side.<BR><BR> | |||

With the addition of the MiSeq, we have reworked how we are processing GAII flowcells. We have been able to create [[BioMicroCenter:PartialFlowcells|'''partial flowcells''']] on the GAII by altering recipes. This has allowed us to move from a model like the HiSeq where we need a full flowcell before we run to a model where we can run as soon as the samples pass quality control, more like the MiSeq. However, unlike the MiSeq, we can run multiple lanes at once. Some critical caveats: First, these methods are not supported by Illumina so we cannot offer to replace failed runs. Second, unlike the HiSeq, the PhiX lane is *not* included. You must choose to sequence a lane of PhiX if you want to do control normalization. Finally, this service is completely "a la carte" so the pricing schema is quite different. <BR><BR> | With the addition of the MiSeq, we have reworked how we are processing GAII flowcells.

Using fewer lanes on each flowcell has allowed us to decrease the cycle time by not imaging all the lanes. In a typical 8 lane run, 20 minutes is spent doing chemistry followed by 40 minutes of imaging (each lane takes ~5 minutes to image). Therefore, a 2 lane flowcell runs twice as fast as an 8 lane flowcell. Also, since the chemistry is not running in to all of the lanes, each sequencing kit can go to a longer read length. The relationships are summarized in the chart on the left. Pricing is set on the number of lanes you are using, the number of days you are running the GAII, and the number of sequencing kits you are using.

The last kit would not be completely used up (you would have an extra 18nt left that would be thrown away).<BR><BR> | ||

Illumina sequencing-by-synthesis is the primary workhorse of the BioMicro Center. These instruments produce millions of reads simultaneously and are used in a very broad spectrum of applications. The Center currently supports 1 NovaSeq 6000, 1 HiSeq2000, 2 NextSeq500s, and 2 MiSeqs.

Typical WorkflowIllumina sequencing at the core begins with library quality control, during which the Center verifies the anchor elements and insert size using qPCR and the Fragment Analyzer. Users may elect to bypass this step if they provide the sample concentration and the concentration they would like to load at. Samples are then entered into the sequencing queue. Typical queues in the BioMicro Center are short, rarely exceeding 1-2 weeks, and samples are frequently run within a couple days. We do guarantee a minimum number of reads per lane provided if: a) BMC performed the QC, b) the samples are high-complexity, especially in the first few nucleotides, and c) the samples are at least 2nM. Illumina sequencing through the BioMicro Center is only available in full lanes and not on a per read basis. You are welcome to collaborate with other laboratories in order to share a lane. However, please be sure to minimize any possibility of cross-contamination of indexes as well as index crosstalk. Data HandlingFollowing sequencing, data is handled using a custom analytical pipeline. If an index was provided, samples are split by index and identified by DNA-ID. FASTQ files and other desired formats will be placed in a delivery folder based on the project name, along with several quality control checks done for the sequencing data.
