The VetBiobank was established in 2007 as part of the VetCore Facility for Research at the University of Veterinary Medicine, Vienna. The primary objectives of the VetBiobank are (1) to achieve comprehensive collections of high quality animal samples to support research projects and (2) to provide biological reference material as controls e.g. for method verification. Currently, collections mainly contain tumor tissues and healthy reference tissues from cats and dogs, but also a small number of biospecimens from other diseases and other species, including macaque, horse, pig, and small companion animals. A total number of around 58000 individual samples are stored. The VetBiobank is partner of BBMRI.at (the Biobanking and BioMolecular resource Research Infrastructure Austria [1]), the Austrian national node of the European research infrastructure BBMRI-ERIC [2], comprising the only member with a focus on veterinary medicine. Funding statement: The VetBiobank is part of the central research facility of the University of Veterinary Medicine, which takes over personnel and running costs. Additionally, the VetBiobank was and is currently supported by two grants from the federal ministry of Austria to BBMRI.at (BMWFM GZ: 10.470/0016-II/3/2013, BMBWF GZ: 10.470/0010-V/3c/2018).
