The Gene Expression Omnibus (GEO) is a public repository managed by the National Center for Biotechnology Information that archives high-throughput gene expression data from various organisms. It facilitates the exploration and analysis of approximately a billion gene expression measurements through user-friendly web tools. GEO allows researchers to submit data in multiple formats and provides extensive querying capabilities via NCBI Entrez databases, enabling users to analyze gene expression profiles and related biological information.

We have answers to the most popular questions from our customers. If you can't find an answer to your question, please contact us.

What is the difference between GEO DataSets and profiles?

GEO DataSets are partitioned into subsets that reflect experimental design. Profiles are flagged as having subset effects if they display differential expression across experimental variables.

What is GEO accession viewer?

Scope allows you to display the GEO accession(s) which you wish to target for display. You may display the GEO accession which is typed into the text box itself (Self), or any (Platform, Samples, or Series) or all (Family) of the accessions related to the accession number typed into the text box.

Is gene expression omnibus reliable?

In the realm of multi-omics research, the Gene Expression Omnibus (GEO) stands as a wealth of valuable data.

Is GEO open access?

GEO is an open-access archive of high-throughput functional genomic data, including all array-based applications and some high-throughput sequencing data.

What is the difference between GEO profile and GEO DataSet?

A DataSet represents a curated collection of biologically and statistically comparable GEO Samples. All Samples in a Dataset reference the same Platform. Datasets can be searched using the GEO Datasets database. A Profile consists of the expression measurements for an individual gene across all Samples in a DataSet.

What is the GEO database used for?

General overview. GEO is an international public repository that archives and freely distributes microarray, next-generation sequencing, and other forms of high-throughput functional genomics data submitted by the research community.

Is GEO-controlled access?

GEO is an unrestricted-access database.

What is gene expression omnibus?

Gene Expression Omnibus (GEO) is a database supported by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) that accepts raw and processed data with written descriptions of experimental design, sample attributes, and methodology for studies of high-throughput gene
