Gene Expression Omnibus (GEO)

GEO is a public functional genomics data repository supporting MIAME-compliant data submissions. Array- and sequence-based data are accepted. Tools are provided to help users query and download experiments and curated gene expression profiles.

Data Types Encouraged/Permitted

From the FAQ (https://www.ncbi.nlm.nih.gov/geo/info/faq.html#kinds), GEO was designed around the common features of most of the high-throughput and parallel molecular abundance-measuring technologies in use today. These include data generated from microarray and high-throughput sequence technologies, for example:

  • Gene expression profiling by microarray or next-generation sequencing (see examples)
  • Non-coding RNA profiling by microarray or next-generation sequencing (see examples)
  • Chromatin immunoprecipitation (ChIP) profiling by microarray or next-generation sequencing (see examples)
  • Genome methylation profiling by microarray or next-generation sequencing (see examples)
  • High-throughput RT-PCR (see examples)
  • Genome variation profiling by array (arrayCGH) (see examples)
  • SNP arrays (see examples) (see human subject FAQ)
  • Protein arrays (see examples)

Data Types Explicitly Prohibited

Geo does not accept partial or heavily filtered data sets (https://www.ncbi.nlm.nih.gov/geo/info/faq.html#summarysubset)
