Array Technology

Gene Microarray Shared Resource (GMSR) renders services using the Affymetrix GeneChip® and Illumina Bead Array® technology platforms.  Learn more about microarray technology platforms used by the GMSR by selecting the links below.



Please contact the core director (harringc@ohsu.edu) for more information as these overviews feature only a subset of the array portfolio serviced by the GMSR.


Microarray: a 2D array, typically on a glass or silicon wafer, upon which genes or gene fragments are deposited/synthesized making them available to bind complementary genomic sequences, if present, in the sample under analysis.

Platform: the type of commercial array technology such as Affymetrix or Illumina, which offers a wide variety of highly reproducible "off-the-shelf" arrays and limited custom array options.  Spotted DNA microarrays are a non-commercial option (not available through the GMSR).
