The Gundersen Foundation BioBank is a tissue repository of biospecimens from more than 20,000 cancer patients. Each is linked to anonymous pathology and clinical records. All biospecimen collection and dissemination protocols are approved by The Gundersen Human Subjects Committee/Institutional Review Board and meet the National Cancer Institute’s Best Practices for Biospecimen Resources.

Formalin-fixed, paraffin-embedded tumor tissue

The BioBank houses formalin-fixed, paraffin-embedded tumors after 20 years of storage in Gundersen’s clinical archive. The BioBank currently holds tumor samples from 20,000 cancer patients and another 1,000 samples are added annually. The tumors are sectioned and stained with hematoxylin and eosin, then examined by a pathologist to confirm or update the original diagnosis.

Minimally ischemic fresh biospecimens

Our BioBank stores biospecimens freshly isolated from patients with a variety of cancer diagnoses and control volunteers. Solid-tumor cold-ischemia times range from four to 20 minutes and are documented. Patient-matched plasma and viable leukocytes are available for all solid tumor specimens. Our storage procedures allow researchers to study samples after thaw.


The BioBank’s searchable database contains clinical and pathology metrics of both the archival and fresh material of the BioBank. The database is a resource, similar to the Surveillance Epidemiology and End Results (SEER) Program, that can be used for clinical research.

Research collaborations

Gundersen Medical Foundation researchers use fresh and archival samples from the BioBank to find new diagnostic markers and therapeutic targets.
