The mission of the University of Arizona Cancer Center Biorepository is to provide high quality cancer and related tissue as well as body fluids to our collaborators. The Biorepository contains tissue that has been preserved by snap freezing in OCT embedding media, snap frozen tissue in vials, as well as formalin-fixed, paraffin embedded (FFPE) tissue. Body fluids include whole blood, serum, plasma and urine. All samples have been de-identified, are reviewed for quality control by a pathologist, have associated clinico-pathologic data and the information is entered into the HIPPA compliant biospecimen software application, Tissue Metrix.
