ArrayExpress -a public repository for microarray data supporting MGED standards
by EMBL-European Bioinformatics Institute

                                   

>> ArrayExpress is an international public repository for well-annotated microarray data, including gene expression, comparative genomic hybridization (CGH) and chromatin-immunoprecipitation (ChIP) experiments.

>> ArrayExpress has three major goals:

1. Serve the scientific community as a repository for data supporting publications
2. Provide easy access to high-quality data in a standard format
3. Facilitate the sharing of microarray designs and experimental protocols

>> ArrayExpress has two major components:

 Experiments : 2484 experiments available [Search experiment, citation, sample and factor annotations]

 Expression Profiles : 180 experiments, 112510 genes available

More characteristics:

• access to well annotated microarray data in a structured and standardised format for research community

• Facilitating the sharing of microarray designs and protocols

• Built on community standards - MAGE, MIAME, Ontology

• Lots of experience of building standards based architecture

• Open source - freely available code ! See the FAQ
