Biomarker Discovery and Validation Facility

The Biomarker Identification and Validation Facility, under the direction of Peter Liu, MD, at the University of Ottawa Heart Institute (UOHI) offers a number of high quality immunoassay services to basic, translational and clinical investigators. We collaborate with regional researchers at the University of Ottawa and other institutions such as Hospital for Sick Children, University of Pennsylvania, and Hospital Universitari Germans Trias i Pujol, Barcelona.

State-of-the-Art Technologies Available

The UOHI Biomarker Facility provides landmark tools for biomarker discovery and validation.

Blood Specimen Processing and Storage:

The UOHI Biomarker Facility provides training and fee-for-service blood specimen processing (plasma, serum, RNA, DNA, et. al.) for researchers who lack the laboratory equipment, skills or time to conduct their own processing. Storage for samples is also available at our facility at a nominal annual fee.


The facility director, Dr, Peter Liu, manager, Dr. Liyong Zhang, and technologist, Dr. Qiujiang Du, are available to advise researchers on determining the best assay, proper collection strategy and the costs involved to address their scientific questions. This consultation starts at the time of research grant preparation, to assist researchers to build in appropriate budgeting for assay costs, including the cost of consumables and reagents necessary for the proper collection of samples for particular assays.
