Concept
Biobank
Summary
A biobank is a type of biorepository that stores biological samples (usually human) for use in research. Biobanks have become an important resource in medical research, supporting many types of contemporary research like genomics and personalized medicine.
Biobanks can give researchers access to data representing a large number of people. Samples in biobanks and the data derived from those samples can often be used by multiple researchers for cross purpose research studies. For example, many diseases are associated with single-nucleotide polymorphisms. Genome-wide association studies using data from tens or hundreds of thousands of individuals can identify these genetic associations as potential disease biomarkers. Many researchers struggled to acquire sufficient samples prior to the advent of biobanks.
Biobanks have provoked questions on privacy, research ethics, and medical ethics. Viewpoints on what constitutes appropriate biobank ethics diverge. However, a consensus has been reached that operating biobanks without establishing carefully considered governing principles and policies could be detrimental to communities that participate in biobank programs.
List of biobanks
The term "biobank" first appeared in the late 1990s and is a broad term that has evolved in recent years. One definition is "an organized collection of human biological material and associated information stored for one or more research purposes." Collections of plant, animal, microbe, and other nonhuman materials may also be described as biobanks but in some discussions the term is reserved for human specimens.
Biobanks usually incorporate cryogenic storage facilities for the samples. They may range in size from individual refrigerators to warehouses, and are maintained by institutions such as hospitals, universities, nonprofit organizations, and pharmaceutical companies.
Biobanks may be classified by purpose or design. Disease-oriented biobanks usually have a hospital affiliation through which they collect samples representing a variety of diseases, perhaps to look for biomarkers affiliated with disease.
