VectorBase maintains a repository for all published and about-to-be-published microarray experiments pertaining to invertebrate vector species. All data is processed through a standard normalisation and analysis pipeline, which enables side-by-side comparison of results from a variety of experimental designs. While we check carefully to ensure that the biological interpretations of the published and VectorBase analyses are qualitatively the same, we advise users to refer to the original authors' data and protocols if in any doubt.

Contribute and have your microarray data displayed at VectorBase! Please see the submission guidelines for further details.

All expression data in VectorBase is held in BASE, a microarray data management and analysis system. Guest access to our BASE server is provided here, however this is read-only and no novel analysis can be performed. Contact the VectorBase help desk to ask for an account with more privileges.

VectorBase has developed an API (upon which this web resource is built) called GESOL (Gene Expression Simple Object Layer). The source code is freely available under the GPL.

Contextual help is provided through mouse-over "tooltips" in many places where you might expect some explanation. Click on the "More info." link in the yellow tooltip popup window to jump to the relevant point in the online user manual for extra helpful information.

• You can perform bulk data query and retrieval with VectorBase's Expression Data BioMart.
• Text file dumps of VectorBase's curated expression data are also available for download.

You may click through to gene expression reports from the VectorBase genome browser. On gene, transcript and protein pages there is a "Gene expression summary" link in the left hand menu. In ContigView (e.g. here), make sure you activate the microarray feature tracks.
