ArrayExpress – functional genomics data

ArrayExpress Archive of Functional Genomics Data stores data from high-throughput functional genomics experiments, and provides these data for reuse to the research community.

Latest News

1 August 2017 - Upcoming Downtime: ArrayExpress submission system will be unavailable from Friday 18 August 2017 until Monday 21 August 2017

Due to essential maintenance, we'll have to shut down the ArrayExpress submission tool Annotare. We would like to ask submitters to log out of Annotare before the maintenance period, and return after the weekend to continue with the submission. All information entered and files uploaded in Annotare are automatically saved, so rest assured that nothing will be lost.

We hope to keep the downtime to a minimum and will be able to accept submissions again from 21 August 2017. We will make timely announcements on our Twitter feed. Sorry for any inconvenience this may cause.
