OHSU has lifted COVID 19 modified operations requirements for research laboratories.  The GPSR has returned to normal operations but is retaining enhanced cleaning procedures and some sample pick-up and drop-off modifications and visitor number restrictions.  Please contact Chris Harrington for questions or more information. Core staff are available by email, phone, and online meeting to plan experiments, advise on sample collection and preparation, review data, and assist with grant development and manuscript preparation.  Please submit service requests on our iLab site.

Gene Profiling Shared Resource

The Gene Profiling Shared Resource (GPSR) is a unit of the Integrated Genomics Laboratory and is located on OHSU Marquam Hill Campus in Richard Jones Hall, room 5330.  We work closely with the Massively Parallel Sequencing Shared Resource and the DNA Services Core 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.

We focus on DNA and RNA isolation and evaluation, cDNA preparation, microarrays, real-time PCR and NanoString nCounter assays.

Please acknowledge support from the core in publications and presentations. 

  • Suggested text: "(Insert appropriate service or platform) were performed in the OHSU Gene Profiling Shared Resource"
    • Services/Platforms: Microarray, qPCR, or NanoString nCounter assays, DNA or RNA isolation services, DNA or RNA quality assessments.
  • The Gene Profiling Shared Resource receives support from the OHSU Knight Cancer Institute NCI Cancer Center Support Grant P30CA069533.
