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

10 July 2019 - A new Single Cell Expression Atlas is out!
The latest release of Single Cell Expression Atlas is now available! It features 99 individually curated single-cell RNA-seq experiments over 11 different species. The analysis pipelines have been updated and now process data from droplet-based technologies such as 10x Genomics and Drop-Seq. RNA-Seq alignment and quantification are handled by Alevin, while filtering and clustering is handled by Scanpy. Links to both can be found in the Single Cell Expression Atlas release notes.
A number of featured landmark studies are also available such as Tabula muris and the Malaria Cell Atlas.
Highlights from ArrayExpress include:
