Definition of Arrayed library

Arrayed library: In genetics, an arrayed library consists of (in technical terms) individual primary recombinant clones which are hosted in phage, cosmid, YAC, or another vector that have been placed in two- dimensional arrays in microtiter dishes (plastic dishes with an orderly array of tiny wells). Each primary clone can be identified by the identity of the plate and the clone location (row and column) on that plate. Arrayed libraries of clones are used for many purposes, including screening for a specific gene or genomic region. The information gathered on individual clones from genetic linkage and physical map studies is then entered into a database and used to construct physical and genetic linkage maps
