studies, it is of increasing importance that these data are captured in public databases
so that researchers can use this information to complement and enhance their own
studies. Many groups have set up databases of expression data, ranging from large
repositories, which are designed to comprehensively capture all published data,
through to more specialized databases. The public repositories, such as ArrayExpress
at the European Bioinformatics Institute contain complete datasets in raw format in
addition to processed data, whilst the specialist databases tend to provide downstream
analysis of normalized data from more focused studies and data sources. Here we
provide a guide to the use of these public microarray resources.</p>
