Gene Expression Omnibus (GEO) is a high-throughput gene expression/molecular abundance data repository, as well as a curated, online resource for gene expression data browsing, query and retrieval. GEO became operational in July 2000.
GEO serves as a public repository for a wide range of high-throughput experimental data. These data include single and dual channel microarray-based experiments measuring mRNA, genomic DNA, and protein abundance, as well as non-array techniques such as serial analysis of gene expression (SAGE), and mass spectrometry proteomic data.
Platform records describe the elements on the array (e.g., cDNAs, ORFs, antibodies, oligonucleotide probe sets) or the list of elements that may be detected and quantified in that experiment (e.g., SAGE tags, peptides). Sample records describe the conditions under which an individual sample was handled, the manipulations it underwent, and the abundance measurement of each element derived from it. Series records define a set of related samples considered to be part of a group, how the samples are related, and if and how they are ordered. A series provides a focal point and description of the experiment as a whole. Series records may also contain tables describing extracted data, summary conclusions, or analyses.
