Research Services - Microarrays for Gene Expression Profiling
Services | Overview | Sample Submission
You must be a registered facility user before submitting any samples for processing. If your laboratory is new to our services, please register here.


The Genomics and Proteomics Core Laboratories offer full laboratory support for gene expression detection on both the Illumina Beadchip and Affymetrix Genechip platforms. We are also available as an informational resource to help you design your microarray experiment and to offer troubleshooting and advice on the technical aspects of utilizing microarray technology in your research.

Microarray Platforms available through GPCL
  • Illumina BeadChip®
  • Affymetrix 3’ IVT arrays
  • Affymetrix WT assay for Exon, GeneST and Tiling arrays

Genomics Manager Debby Hollingshead is available to go over the specifics of any project and review how the GPCL might best facilitate your research progress. She can be contacted at: or 412-648-1284.

Data Analysis

The Bioinformatics Analysis Core can provide assistance with the complex analysis of microarray expression data. Their services cover everything from consulting on experimental design to production of publication ready figures. If you would like to utilize their services for microarray analysis, please contact Jim Lyons-Weiler to arrange a consultation. This consultation will be of most value to you if undertaken before you begin your experiments.

Turn around time

GPCL works on a first come first serve basis. Therefore the exact turn around for any submission will depend on the amount of work ready and waiting to be performed when your samples arrive. Microarray data will be returned within one month of submission, but may be completed sooner if there is no queue.
