The OHSU Gene Profiling Shared Resource (GPSR), formerly the Gene Microarray Shared Resource,
functions as a full-service genomics facility providing research scientists and clinicians with services for RNA expression profiling and DNA variation analysis. Technologies available through the core include two microarray platforms, Affymetrix and Illumina, a high throughput qPCR system, and a short read next generation DNA sequencing instrument.

Support and consultation for RNA and DNA isolation and RNA/DNA quality assessment also available


The GPSR is located on OHSU Marquam Hill Campus in Richard Jones Hall room 5390


  • Expression Profiling: mRNA and microRNA expression profiling, including options for whole transcript analysis and alternative transcript/exon analysis

  • DNA Variation Analysis: Whole genome and targeted SNP genotyping and copy number analysis with microarrays and PCR assays

  • RNA and DNA Isolation: Support available for RNA/DNA isolation in connection with microarray, sequencing or Q-PCR projects; automated protocols for QIAGEN spin-column kits, including PAXGene Blood RNA kits

  • RNA/DNA Assessment: Quantification and  size or quality assessment of RNA and DNA samples


  • QuantStudio qPCR System
  • Caliper LabChip GX System

For all other service and instrument access inquiries, please contact the GPSR Director.

New Assays and Technologies

Genome-wide Profiling of Human Transcript Isoforms

New  comprehensive transcriptome array from Affymetrix– GeneChip Human Transcriptome Array 2.0.  Array design includes exon andsplice junction probes and provides data about all transcript isoforms.

Affymetrix GeneChip Human Transcriptome Array 2.0

To facilitate analysis of array data, Affymetrix has just released easy-to-use Transcriptome Analysis Console (TAC) software for differential expression analysis and data visualization.  Contact Affymetrix or Amiee Potter (potteram@ohsu.edu) for more information.
