RNA and DNA Isolations and Gene Profiling Services

RNA and DNA Services is a unit of the IGL and includes all services and technologies formerly provided through the Gene Profiling Shared Resource and the DNA Services Core. We are located on OHSU Marquam Hill Campus in Richard Jones Hall, room 5330 and 5390. Our unit focuses on RNA and DNA isolation and evaluation, 10X Genomics single-cell cDNA preparation, real-time PCR and NanoString nCounter assays. We work closely with the other units of the IGL to provide support and services, from specimen processing through data generation and validation.  Training and access to many of the core's advanced technology systems is also available.

The Integrated Genomics Laboratory RNA and DNA Services unit is now directed by Robert Searles. Please contact the lab manager, Britt Daughtry, if you have any questions. Please submit service requests on our iLab site.

Please acknowledge support from the core in publications and presentations.

Services we offer

Full service support for qPCR mRNA and microRNA expression profiling. Self-service use on both the Quantstudio qPCR systems and the Nanostring SPRINT Profiler.

Multiple single-cell and single-nuclei cDNA preparation options are available on the 10X Genomics Chromium Controller. This service is coordinated with the Massively Parallel Sequencing Shared Resource (MPSSR) for library preparation and sequencing.  To initiate service, please see the MPSSR's iLab site.

Full service support for targeted SNP genotyping qPCR assays. Self-service use on both the Quantstudio qPCR systems and the Nanostring SPRINT Profiler.

Support available for RNA/DNA isolation for sequencing, qPCR or other gene profiling and DNA analysis applications; automated protocols for QIAGEN spin-column and magnetic bead-based protocols, including for PAXGene Blood RNA tubes and FFPE samples. Services for co-isolation of RNA and DNA as well as RNA and genomic DNA clean-up services are also available.

RNA and DNA Assessment: Quantification, size, and/or quality assessment of RNA and DNA samples for targeted profiling and genotyping projects.

We offer a human cell line authentication (CLA) service that uses Promega's GenePrint® 10 system to confirm the identity of human cell lines through short tandem repeat (STR) analysis and to detect the presence of cell line contaminants. This service provides co-amplification and detection of 9 STR loci plus Amelogenin (the gender determining locus). 

We perform cell line authentication using a 48-capillary Applied Biosystems 3730xl DNA Analyzer.  Several levels of service are available to match your research needs. Please contact Alex Klug with questions or to provide feedback on CLA services.

  • Core leadership change as of January, 2024
    • Chris Harrington stepped down from her leadership role for the Gene Profiling Shared Resource and the DNA Services Core at the end of 2023.  Robert (Bob) Searles is now the director of both of these Integrated Genomics core units which have been combined into one operating unit and renamed RNA and DNA Services. All prior services, except for microarray profiling, will continue under Bob’s leadership.
  • April 25, 2024: OHSU Epigenetics Symposium
    • The OHSU Epigenetics Symposium, organized by the KCVI Epigenetics Consortium, will feature keynote addresses by Dr. Marisa Bartolomei (University of Pennsylvania) and Dr. Joe Ecker (UC San Diego). The program also includes presentations from researchers focused on epigenetics and a poster session featuring graduate students, postdocs, and research staff. A reception will be held at the conclusion of the event.
  • Winter 2023-2024 Integrated Genomics Laboratory Newsletter
  • Reciprocal core rate agreement for five Oregon universities
    • Five Oregon universities participate in a reciprocal internal rate agreement for the use of research core facilities and shared service units for researchers among the institutions

Instrument access for trained users

Assay and technology highlights

Specializing in DNA isolation from human blood and saliva as well as RNA isolation from a variety of specimens including FFPE tissue. Process hundreds of samples a week, reduce isolation turn-around time as well as per sample cost with the added benefit of consistency and reproducibility. For more information, please see the High-Throughput DNA/RNA Isolation flyer, or contact Britt Daughtry.

Effective January 1st, 2024, microarray services are no longer offered by the Gene Profiling unit of the Integrated Genomics Laboratory. All microarray data from past project is archived in the the IGL's data storage system.

Several partnering labs offer Affymetrix (ThermoFisher) gene level whole transcriptome profiling at low cost.  For more information about which labs can offer this service please reach out to Britt Daughtry.
