CEACAM5 refers to a protein target that is studied across multiple biological contexts; annotations and nomenclature can vary by species and isoform. This product corresponds to the Homo sapiens (Human) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt\/NCBI) and the recent literature for the specific organism and isoform.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eMapping pathway dependencies and signaling networks that drive tumor growth and drug resistance.\u003c\/li\u003e \u003cli\u003eDeveloping and benchmarking biomarker assays (e.g., immunoassays or binding reagents) for candidate targets.\u003c\/li\u003e \u003cli\u003eCharacterizing protein variants, domains, or interaction partners relevant to targeted therapeutics and precision oncology.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eAssay and standard development for immunoassays or binding-based detection methods.\u003c\/li\u003e \u003cli\u003eProtein–protein interaction studies (e.g., receptor–ligand or complex assembly) using purified components.\u003c\/li\u003e \u003cli\u003eStructure–function analysis, including domain mapping or evaluation of sequence variants.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn quantitative assay development, changes in binding or activity readouts are typically interpreted relative to appropriate negative\/positive controls and, where possible, orthogonal assay formats that support the same conclusion.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eRecombinant constructs may represent a defined region (domain) rather than the full-length protein; interpret results in the context of the expressed region.\u003c\/li\u003e \u003cli\u003eTag or fusion elements can aid purification and detection but may influence binding surfaces or oligomerization; consider tag controls when relevant.\u003c\/li\u003e \u003cli\u003eSpecies and isoform differences can affect interaction partners and post-translational modifications; align experimental controls to the intended biological context.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for P06731 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P06731\/entry - NCBI Gene search (CEACAM5) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CEACAM5 - PubMed search (CEACAM5) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CEACAM5 - RCSB PDB search (CEACAM5) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=CEACAM5 - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065268068717,"sku":"CSB-YP005165HU-1MG","price":2474.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065383281005,"sku":"CSB-YP005165HU-100UG","price":576.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065383313773,"sku":"CSB-YP005165HU-20UG","price":306.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-YP005165HU-SDS.jpg?v=1772476390","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-carcinoembryonic-antigen-related-cell-adhesion-molecule-5-ceacam5-e398k-bhp10508763","provider":"BioHippo","version":"1.0","type":"link"}
