Data Retention

As a reminder to our users:  We do NOT store your data long term.  Once your runs are finished and your data given to you, we reserve the right to delete it from our servers to recover space for ongoing runs for other users.  It is the responsibility of the grant holder to archive their data, not the core labs.  We cannot maintain a server farm to archive data for everyone.  For archival purposes, we suggest users contact CHPC about creating storage space for their data there.

Contact Derek Warner for further information or with any questions.

Short read sequencing on the Element Biosciences AVITI

The Element Biosciences AVITI is a recently purchased instrument that is cutting edge in the short read market.  The AVITI is a mid sized sequencer, so flow cells provide ~1 billion reads/run or less.  This makes it ideal for rapid turnaround times on projects because we are not waiting long periods of time to fill very large flow cells.  Typically sequencing runs can be done from library receipt to data delivery in a matter of days.  This instrument provides reads that are mostly in the Q40 range rather than the historically standard Q30 output from other competing sequencers, providing the user with exceptional data quality from their samples.  The AVITI is also more tolerant of GC composition than standard sequencing.  This allows for better sequencing overall as coverage will be more uniform across templates, especially difficult templates.  We have seen this specifically in 10x Genomics libraries where more genes per cell are actually seen vs. Illumina sequencing.  In addition to these differences, we have also seen that  the AVITI is able to sequence through difficult regions (like homopolymer stretches) and then continue to provide usable sequence afterward.  The AVITI is also able to sequence using larger insert sizes which may provide benefits in mapping data (for an example, check out the Google Deep Variant paper here).  We have sequenced successfully in our lab with 1000bp inserts so far.  We do not yet know where the upper limit is.

Long read sequencing with Oxford Nanopore Technologies (ONT)

Oxford Nanopore Technologies (ONT) technology provides multiple sequencing options provide for the ability to answer multiple questions.  The P2Solo instrument we just recently received is able to run two PromethION flow cells at once.  Each flow cell is sufficient to sequence one human genome.  Smaller projects can be barcoded and combined into a single run.  The instrument will sequence the DNA and also can obtain methylation state of the DNA at the same time.  Because it is based on a pore rather than an enzymatic method, the ONT devices are the only systems on the market that can directly read RNA.  The ONT system also has the unique ability to allow for sequencing of mostly regions of interest and throw out reads from areas outside the targeted regions.  This mode is called adaptive sampling.  A bed file is created with some buffer areas around your target regions.  This bed file informs the sequencer which sequences are targeted.  The sequencer reads the sequences as they pass through the pores in real time and after around 400-500 bases are read, if they don’t match the target regions, the sequencer reverses polarity of that one pore and ejects the DNA strand, making that pore available again for a different strand of DNA to enter.  In this way, target regions can be enriched during the run without any special captures or amplification approaches.  

Single cell sequencing with the 10x Genomics Chromium Controller

The 10x Genomics Chromium Controller is used for single cell analysis.  Researchers are using this to evaluate cell types from different organs.  Our controller can be used for all 10x protocols except spatial and fixed cells at this time.  The DNA Sequencing core works hand in hand with the HSC Flow Cytometry core and HSC Bioinformatics core to provide a sample to data experience for our users.  

Sanger sequencing on the Applied Biosystems 3730xl

The ABI 3730xl is the workhorse that has been used by industry for many years now and still continues to put out quality data for researchers here on campus and the surrounding areas.  Turn around time on samples can be as quick as the same day.  

In addition to the above, the DNA Sequencing core is always interested in helping with experiments that may not fit into the standard box envisioned by manufacturers of instrumentation and as such is always willing to discuss and help execute plans for novel and exciting additions to the technologies and techniques already in use in our core.  Feel free to some talk to us about your project.

Requesting Services

If you are new to the Cores, you must complete a work authorization form through the Work Authorization System prior to requesting services. Work authorizations may be used for any services offered by facilities managed by HSC Cores. After your work authorization has been approved you will be able to login to the Resource System.

Existing users may login directly to the Resource Scheduling System to schedule or order services. This system is cores-wide and uses University of Utah uNID authentication.

Sanger Sample Submission Guidelines

PCR Products

  • Quantitate using a gel (nanodrop isn’t reliable with PCR products)
  • For small templates use 50ng PCR product (please clean it up first as left over primers can mess up sequencing) and 4 picomoles of primer (4uL of a 1uM aliquot)
  • For larger templates, it is recommended to go high as 150ng (for approx. 2kb).  Otherwise somewhere between the minimum and this will likely work. Use 4 picomoles of primer (4uL of a 1uM aliquot).
  • Add molecular grade water to a total volume of 10uL

Plasmids

  • For small samples (2-6kb) 600ng of product and 4 picomoles of primer (4uL of a 1uM aliquot) is recommended.
  • For larger samples use more template/product (7-8kb: 700-800ng recommended, 9-10kb: 900-1000ng recommended) with 4 picomoles of primer (4uL of a 1uM aliquot).
  • Add molecular grade water to a total volume of 10uL

Labeling your samples

Retrieving your data

The data is available the same night the run completes. The plate status, however, won't change until it has been reviewed by our staff. To find your data before we mark it as completed:

  1. Login to the Resource system
  2. Go to the "Sequencing Order Manager" (Located in the "DNA Sequencing" core)
  3. Change the View Mode from "Viewing: Completed" to "Viewing: Processing"
  4. Locate your order in the list and click on the "Detail" button with the magnifying glass
  5. Change the active tab (Green) from "Overview" to "Results". From the results tab you can download the whole dataset or the files for individual samples.

Once we have checked the plate and determined which samples we feel we need to redo your order will be marked as completed. To retrieve data from completed orders:

  1. Login to the Resource system
  2. Go to the "Sequencing Order Manager" (Located in the "DNA Sequencing" core)
  3. From the "Viewing: Completed" View mode you will see completed orders
  4. Locate your order in the list and click on the "Detail" button with the magnifying glass
  5. Change the active tab (Green) from "Overview" to "Results". From the results tab you can download the whole dataset or the files for individual samples
