Biobanks are entities responsible for the management of biological resources. These structures collect, classify and index fluid or tissue samples taken from living bodies (animals, plants and humans). They are essential for the support of medical research since their resources are made available to the scientific community.
After a biopsy, or other procedures to recover a human sample, a sample may be kept, with the patient's consent, for research purposes. This allows researchers to work on suitable samples, such as tumour or blood samples.
Samples, after collection, must be stored under certain conditions, depending on their type and shelf life, to ensure their viability. Tissue samples, for example, can be stored at room temperature, while blood samples will often be stored at very low temperatures.
