A biorepository is a facility that collects, catalogs, and stores samples of biological material for laboratory research. Biorepositories collect and manage specimens from animals, plants, and other living organisms. Biorepositories store many different types of specimens, including samples of blood, urine, tissue, cells, DNA, RNA, and proteins. If the samples are from people, they may be stored with medical information along with written consent to use the samples in laboratory studies.
