Search for array designs

Array designs, also known as platform designs, can be searched on the Arrays page.

Toggle the check box "ArrayExpress data only" to search for array designs submitted directly to ArrayExpress, or those imported from NCBI Gene Expression Omnibus (see the GEO data help page for more details on the import process).

You can search by the array design's accession, species, name/description and the submitter's contact details:

  • ArrayExpress accession: It has a format of A-xxxx-n, where xxxx represents a four letter code and n is a number e.g. A-MEXP-1234, A-AFFY-44.



  • Organism: The name of the organism for which the microarray probes were designed. You can use either common name or Latin name. E.g. Homo sapiens, Saccharomyces cerevisiae, dog because search term expansion by Experimental Factor Ontology will match common names automatically with Latin names as synonyms (highlighted green in search results).



  • Array name and description: You can search for terms in the array's name (title) and description, e.g. the array's manufacturer, name of the lab which printed the microarray, catalogue number, Design ID/Grid name (for Agilent arrays), the purpose of the array (e.g. CGH, expression). Exact and synonym matches to search terms will be highlighted yellow and green respectively:



    If you are not sure about the terms to use, you can do "wild card" search, i.e. expand the search space by including asterisks (*). In the following example, both CGH and aCGH (in A-MEXP-1849) are matched because of *CGH:


    Here is another example of searching with asterisks. Both Human HT-12 and HumanHT-12 are matched:


  • Array submitter's name: The name or email address of the person who submitted the array design to ArrayExpress.
