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.
11 February 2019 - ArrayExpress - update paper published!
A new publication describing the development and future plans for the ArrayExpress archive and database service has recently been published in Nucleic Acids Research: ArrayExpress update - from bulk to single-cell expression data.
Read it to discover the breadth of the data contained within the archive and how it has developed over the years to reflect the latest technologies in functional genomics, in particular, single cell sequencing, and to learn about the improved functionalities of its linked submission tool, Annotare.
Please cite this paper in your publications when referencing ArrayExpress.
