What is ArrayExpress?

ArrayExpress is a database of functional genomics experiments. The data and information about the experiments are stored according to the MIAME and MINSEQE guidelines for microarray and sequencing experiments (Figure 2).

The experiments in ArrayExpress are submitted by researchers or are imported from other functional genomics databases e.g. NCBI GEO

Why do we need ArrayExpress?

ArrayExpress was established to make data from high-throughput technologies available to the scientific community. It provides easy access to well-annotated functional genomics data in a structured and standardised format, and facilitates sharing.

What can I do with ArrayExpress?

ArrayExpress can be used to:

  • find functional genomics experiments;
  • download functional genomics data;
  • store your functional genomics data.
