This glossary was created by extracting and combining information from various resources available from other biorepositories at the National Institutes of Health (NIH), standardized definitions from Federal documents, the National Cancer Institute (NCI) Thesaurus and other widely used sources or reports specific to biorepository resources such as the International Society for Biological and Environmental Repositories' (ISBER) Best Practices for Repositories, Fourth Edition (2018).
Access. The right to obtain or make use of or take advantage of something (as services or membership); the right to enter (NCI Thesaurus).
Aerosol. A fine mist or spray that contains minute particles (Centers for Disease Control and Prevention (CDC) Special Pathogens Branch, Glossary of Terms, http://hickmancharterscioly.pbworks.com/f/Glossary+_+CDC+Special+Pathogens+Branch.pdf ).
Age of Majority. The age—usually 18 or 21 years—at which a person achieves full legal rights to make one's own decisions, enter into contracts, and be held personally accountable for the consequences of one's actions (Taber's Medical Dictionary).
Aliquot. 1. Pertaining to a portion of the whole; any one of two or more biospecimens of something, of the same volume or weight (NCI Thesaurus). 2. A process wherein a biospecimen is divided into separate parts which are typically stored in separate containers as individual biospecimens (ISBER 2018).
Analyte. A substance or chemical constituent that is determined in an analytical procedure. Component represented in the name of a measurable quantity. This includes any element, ion, compound, substance, factor, infectious agent, cell, organelle, activity, property, or other characteristics which are to be determined. (ISBER 2018).
Ancillary Study. An additional or secondary trial that was not part of the original study design. An entirely new study, approved or funded by NIA, which will use the data and biospecimens collected by the main study. Ancillary studies attempt to answer questions not resolved through the main study.
Annotation. Explanatory information associated with a biospecimen (NCI Best Practices working definition).
Anonymized Biospecimens. 1. Anonymized data and biospecimens are initially single or double coded but the link between the subjects' identifiers and the unique code(s) is subsequently deleted. Once the link has been deleted, it is no longer possible to trace the data and biospecimens back to individual subjects through the coding key(s). Anonymization is intended to prevent subject re-identification. (Guidance for Industry: E15 Definitions for Genomic Biomarkers, Pharmacogenomics, Pharmacogenetics, Genomic Data and Sample Coding Categories. FDA April 2008). 2. Involves completely removing all identifying information from specimens and data, eliminating the possibility of re-identifying the participant or re-contacting donors. This also precludes any return of research results, possibility for donor withdrawal, and limits the use of the specimens in future research. (ISBER, 2018)
Anonymous. Identifiable personal information was not collected for the specimens and associated data or, if collected, was not maintained and cannot be retrieved, such that there is no way to trace the identity of the subject from whom the specimens were obtained. (ISBER, 2018)

Cryoprotectant. An additive or mixture of additives that allow living cells, tissues, organs, and organisms to survive exposure to cryogenic temperatures, of which the main type is a colligative cryoprotectant. This is a protective additive that must be able to penetrate the cell, applied to prevent damage caused by excessive cell volume changes and the toxic concentration of solutes (i.e., colligative injury). An osmotic cryoprotectant is an additive that does not penetrate the cell. It confers additional protection by osmotically withdrawing water from the cell (osmotic dehydration), consequently reducing the amount of water that is available to form ice.
