A microarray database is a repository containing microarray gene expression data. The key uses of a microarray database are to store the measurement data, manage a searchable index, and make the data available to other applications for analysis and interpretation (either directly, or via user downloads). Microarray databases can fall into two distinct classes: # A peer reviewed, public repository that adheres to academic or industry standards and is designed to be used by many analysis applications and groups. A good example of this is the Gene Expression Omnibus (GEO) from NCBI or (ArrayExpress ) from EBI. # A specialized repository associated primarily with the brand of a particular entity (lab, company, university, consortium, group), an application suite, a topic, or an analysis method, whether it is commercial, non-profit, or academic. These databases might have one or more of the following characteristics: # * A subscription or license may be needed to gain full access, # * The content may come primarily from a specific group (e.g. (SMD ), or (UPSC-BASE )), the Immunological Genome Project () # * There may be constraints on who can use the data or for what purpose data can be used, # * Special permission may be required to submit new data, or there may be no obvious process at all, # * Only certain applications may be equipped to use the data, often also associated with the same entity (for example, (caArray at NCI ) is specialized for the caBIG), # * Further processing or reformatting of the data may be required for standard applications or analysis, # * They claim to address the 'urgent need' to have a standard, centralized repository for microarray data. (See (YMD ), last updated in 2003, for example), # * There is a claim to an incremental improvement over one of the public repositories, # * A meta-analysis ''application'', which incorporates studies from one or more public databases (e.g. (Gemma ) primarily uses GEO studies; (NextBio ) uses various sources) Some of the most known public, curated microarray ''databases'' are: * For a directory of Microarray Databases, see: ==See also== *(ArrayExpress: Quick Tour on EBI Train OnLine ) *(Exploring functional genomics data with the ArrayExpress Archive on EBI Train OnLine ) *(Investigating gene expression patterns with the Gene Expression Atlas on EBI Train OnLine ) *(ArrayExpress:Submitting data using MAGE-TAB on EBI Train OnLine ) *Biological database *DNA microarray *DNA microarray#Data warehousing *(ArrayExplorer ) - A free tool to compare microarrays side by side. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Microarray databases」の詳細全文を読む スポンサード リンク
