## Description

These tracks display microarray data hybridized to the Affymetrix Human Exon 1.0 GeneChip. In contrast to traditional microarrays, which are designed to measure overall gene expression, the Affymetrix exon arrays contain separate probesets for each exon. This allows large-scale measurement of alternative splicing, alternative polyadenylation, and alternative promoter usage. Additionally, analysis of the constitutive exons (those included in all transcripts) offer accurate measurement of overall gene expression levels. Further information on the design and content of exon arrays can be found here.

## Display Conventions

Items on these tracks represent exon array probesets. For information regarding specific microarray probesets, turn on the Affy Exon Probes track, which can be found inside the Affy Exon supertrack in the Expression track group.

## Credits

These data were generated and analyzed as part of the ENCODE project, a genome-wide consortium project with the aim of cataloging all functional elements in the human genome. This effort includes collecting a variety of data over a specific set of cell types. Consequently, data related to these tracks be available under ENCODE tracks.

## Data Release Policy

Data users may freely use ENCODE data, but may not, without prior consent, submit publications that use an unpublished ENCODE dataset until nine months following the release of the dataset. This date is listed in the Restricted Until column on the track configuration page and the download page. The full data release policy for ENCODE is available here.
