01 General Information

Please see this page: Getting Started. You will find information on how to set up an account, billing, data storage & distribution, scheduling, equipment & training, bulletins, research support, seed grants, and more.

Please find all the required information on sample submissions and project scheduling on this page http://dnatech.genomecenter.ucdavis.edu/sample-submission-scheduling/.

The Genome Center Cores provide services at three recharge rate scales. The University of California rate scale (UC rates) do apply to all projects paid through UC-system accounts. Non-profit/academic rates do apply to all other non-profit research including government projects. The industry rates apply to all projects paid from for-profit businesses or institutions.

The invoicing process will vary slightly for UC Davis clients, other UC system customers, and non-UC customers.

UC Davis customers:

  1. Once data are delivered to you, the project billing information will be entered into the secure web portal at http://cores.genomecenter.ucdavis.edu/ , where you can view it.
  2. In the first days of a month your UC Davis DaFIS/KFS accounts will be billed processed.
    Please note that the billing data entry is recorded and that this is sufficient for expiring grants. The final processing can occur after the deadline (usually up to two months).

Other UC system customers:

  1. Once data are delivered to you, the project billing information will be entered into the secure web portal at http://cores.genomecenter.ucdavis.edu/ , where you can view it.
  2. In the mid of the following month the UC inter-campus transaction system will bill your account via an ITF.

Non UC-customers (academic, non-profit and industry):

  1. Once data are delivered to you, the project billing information will be entered into the secure web portal at http://cores.genomecenter.ucdavis.edu/ , where you can view it.
  2. You then have access to pay by credit card immediately. The Genome Center portal will direct you to a secure credit card payment site (please note, no notification is sent at this time, but the invoice is view-able when logged in to your Genome Center account).
  3. Customers are sent an email notification within the first three days of the following month that lets them know their order is available to pay via credit card for 30 days. This email also requests customers notify our business administration: gccoreadmin@ucdavis.edu (530) 754-9648.
  4. Those that did not pay via credit card during the 30-day period are now manually invoiced and the credit card option in the Cores portal is turned off.
    1. The first days of the month are when invoices are processed by our business administration.
    2. Invoice customers generally receive their invoices after the 15th each month.


Non UC system users, both non-profit and for-profit organizations, can request invoicing (after data delivery) simply by entering the terms “credit card” or “invoice” in the account fields of the submission form.  You can also set up a purchase order (a “PO”) beforehand.
We require purchase orders only for institutions outside the US.  Please email the POs to both Jen Stevens at our Business Office (gccoreadmin@ucdavis.edu) and us at dnatech@ucdavis.edu.

A purchase order is a simple  letter from your financial administrators listing the requested services and prices.
It has to include the full contact information of your financial administrators as well as the name and institution of the Principal Investigator (“PI”).
The PO has to state the specific services requested from us – essentially repeating the information provided in quotes from us or from the recharge rate listing from our webpage.
POs should have an ID number on them which your administration can generate according to their preferences.

Please feel free to use your standard PO forms. This purchase order template, with all the required and suggested fields, is a suggestion:  http://dnatech.genomecenter.ucdavis.edu/wp-content/uploads/2016/04/purchase-order-DNATech3_1.doc

Please see this page for more information on POs: http://blog.procurify.com/2013/09/23/all-you-ever-needed-to-know-about-purchase-orders/
We did modify a generic PO template from here: http://www.vertex42.com/ExcelTemplates/excel-purchase-order.html

Several pieces of equipment are available for use during normal working hours for a nominal ‘instrument use’ fee. To use the Shared Equipment, first you will need to be trained by Core staff (subject to a ‘training fee’, good for one year). Your PI will need to create an account with the Genome Center and supply a DaFIS # or PO for billing. Visit our login site and follow the instructions for “Creating an Account.” Also visit here to learn more about the Training and Use of Core Facility Equipment. To schedule a time for instrument training, please email the responsible staff member.


We can provide better advice on appropriate or optimal sequencing options if you provide us important background information on your project. We suggest using the questions below as a starting point for inquiries.

Information requested for RNA-sequencing projects:

  • Which species are you studying (prokaryotic or eukaryotic)?
  • From which sample types will the RNA be isolated (e.g. tissues, cell cultures, whole organisms)?
  • What is the objective of the study (e.g. differential gene-expression (DGE) study, gene annotation, identification of iso-forms)?
  • For differential DGE studies: Are you interested only in gene-level DGE, or do you want to study the expression of the different transcripts of genes? Are you interested in non-coding RNAs?
  • Do you expect lowly expressed genes to become important for your study?
  • How closely are related (genetically) are the biological replicates?
  • Do you expect to induce strong phenotypic changes by the varying treatments?
  • What total RNA amounts do you expect to extract from the samples?
  • What is the expected integrity of the RNA samples (e.g. RIN-scores)? Do you expect potentially interfering chemicals in the samples (e.g. phytochemicals)?
  • How many samples do you want to study? Will the samples be available at the same time?

RNA-seq options are described on two pages: RNA-seq and 3′ Tag-Seq Gene Expression Profiling.

Information requested for DNA-sequencing projects:

  • Which species are you studying (prokaryotic or eukaryotic)?
  • What type of samples are you going to submit (e.g. genomic DNA, amplicons, metagenomic samples, purified strain or population samples)?
  • What is the expected genome size? What genome coverage are you aiming for?
  • What is the objective of the study (e.g. SNV variant analysis, genotyping, de novo genome assembly, structural genome variants, metagenomic analysis)?
  • For de novo genome assemblies: Are you interested in genic regions or do you require the full genome sequence? Do you require the ordering of the assembly scaffolds?
  • What DNA amounts do you expect to extract from the samples?
  • What is the expected DNA sample integrity (fragment sizes)? Do you expect potentially interfering chemicals in the samples (e.g. phytochemicals)? What protocol are you using for the DNA isolation?
  • How many samples do you want to study?

Most DNA-Seq options are described here.

Samples will be stored in the freezer for no longer than one year past the date of submission.  DNA samples and sequencing libraries will be stored in a -20 degree C freezer.  RNA samples are stored in a -80 C freezer. Please arrange for a pickup of your samples in the weeks immediately after data delivery.

We are available every workday from 9 am to 5 pm.
We will be closed on university holidays.  These are listed here:  http://registrar.ucdavis.edu/calendar/holidays.cfm

This page informs on the data processing included with our sequencing services and bioinformatic analysis options.
This page informs on the data processing options for Infinium genotyping data.

Our neighbors from the Bioinformatics Core provide sequence data analysis, statistical evaluations, consulting, and training to help you get the most out of your data. Please contact us for joint consultations with the Bioinformatics Core staff and also for complete analysis packages including sequencing and bioinformatics (e.g. differential gene expression, variant calling).



Please support us by acknowledging our services in your publications. We have received NIH funding for the purchase of some of our instruments and this support should be mentioned. Please add a sentence like this to your acknowledgments: “The sequencing was carried out at the DNA Technologies and Expression Analysis Cores at the UC Davis Genome Center, supported by NIH Shared Instrumentation Grant 1S10OD010786-01.”
Acknowledgments like this constitute a big support for future NIH instrumentation grant applications.

We ask you to mention our services in the acknowledgments of your publications.  This will support our applications to instrumentation grants and thus help to improve our services.
Please see the the details here.
If you feel we contributed intellectually to your project it is appropriate for us to share authorship.  If you have any questions please talk to us about it. For a more detailed discussion of authorships when using a core facility please have a look at the ABRF Authorship Guidelines. These are the community standards most core facilities follow when there are questions about authorship.

Seed Grants

Yes, the Genome Center invites proposals for pilot projects that merit support by the Genome Center. These seed grants award up to $2,000 to spend at any of the Cores; it is also possible to apply for grants at multiple Cores to UC Davis labs.  The Genome Center seed grants are available all year round. They are meant to either introduce UC Davis labs to high-throughput sequencing or genotyping methods, or to help establish new methods.  They will fund up to $2000 per project.  Equivalent pilot grants are also available through the Bioinformatics core. Please see: http://dnatech.genomecenter.ucdavis.edu/2014/07/31/2015-genome-center-cores-pilot-grant-program/ . A seed grant application should be about one page long and include an outline of the project including the planned data analysis, a sentence on how the project would fit in with the goals of the GC seed grants,  a listing of the specific services to be provided by our Core, as well as a budget (including an account number in case the costs exceed the grant amount).

The BGI@UCDavis was located in the School of Medicine on the Sacramento campus and did provide sequencing services for large scale sequencing projects up until September 2015. This BGI facility is now closed.  Since our DNA Technologies Core operates the latest generation of sequencers (HiSeq3000/4000),  which offers a 7 times increased throughput compared to the previous generation, our Core is now taking on also large sequencing projects. The DNA Technologies Core is offering all the services previously provided by the BGI@UCDavis. In addition we offer many specialized services and support for custom sequencing projects.
