This project is one part of the National BioResource Projects (NBRP) in Japan for more than 20 species including animals, plants, microbes, tissues and DNAs. It is founded by the Japanese Ministry of Education, Culture, Sports, Science and Technology (Monkasho) and started in 2002.

The Institute of Laboratory Animals, Graduate School of Medicine, Kyoto University, is the central facility for the species rat. The 2nd term of NBRP-Rat has started in 2007, following the 1st term (2002-2006).

The major goals of NBRP-Rat are the collection, preservation and supply of rat strains. The repository includes strains from Japan and abroad, spontaneous mutants, congenic and recombinant strains as well as transgenic and mutagenized rats. Deposited rat strains are not only conserved as cryopreserved embryos and sperm. Many reference and frequently used rat strains are also maintained as living animals under SPF conditions. About all strains, quality assurance through microbial and genetic monitoring are conducted.

Furthermore, NBRP-Rat provides a unique database on various rat strain phenotypes accompanied with basic genetic information. This allows scientists the selection of standardized and research specific strains. From the 2nd term of NBRP-Rat, the Rat Resource and Research Meeting was initiated as exchange meeting for information around the rat. This project promotes further utilization of the rat as a research tool in many fields of science.
