Search EBI Expression Atlas — ~4,500 curated gene/protein expression experiments (baseline & differential) across species, tissues, and conditions. Filter by keyword (matches description/experimental factors), species (e.g. “Homo sapiens”, “Mus musculus”), and/or type (“Baseline” or “Differential”). Returns accession, description, species, type, assay count, and factors. Keyless. Complements UniProt/Ensembl.
