[Constitution of a bank of biological material. Practical aspects].

A bank of biological materials (Biorepositories) aims to collect and preserve in a variable time period (from few days to several years) various biological samples (serum, plasma, cells, DNA, etc) with a view to make subsequent analysis associated with a powerful information management system, enabling the storage of data related to the biological specimens. The bioprocessing of Biorepositories is complex and include: specimen collection, processing issues, identification process, design equipment: liquid nitrogen and mechanical freezers, storage techniques, bioclinical information and biological specimens inventory management systems, quality assurance programs, ethical and legal problems.
