BCoV-N 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 Bovine coronavirus (strain LSU-94LSS-051) (BCoV-LSU) (BCV) 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\u003eUsing recombinant proteins to enable quantitative binding measurements and reagent benchmarking.\u003c\/li\u003e \u003cli\u003eStudying domain- and isoform-specific effects in pathway models and interaction networks.\u003c\/li\u003e \u003cli\u003eDeveloping robust, reproducible assays that connect molecular readouts to cellular phenotypes.\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 \u003cli\u003eE. coli expression can limit eukaryotic post-translational modifications; for modification-dependent biology, interpret results accordingly.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for Q9QAR1 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/Q9QAR1\/entry - NCBI Gene search (N) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=N - PubMed search (N) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=N - RCSB PDB search (N) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=N - PubMed search (BCoV-N) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=BCoV-N --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065285402989,"sku":"CSB-EP889516BJI-1MG","price":1812.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065424535917,"sku":"CSB-EP889516BJI-100UG","price":419.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065424568685,"sku":"CSB-EP889516BJI-20UG","price":224.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP889516BJI-SDS.jpg?v=1772476446","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-bovine-coronavirus-nucleoprotein-n-bhp10509378","provider":"BioHippo","version":"1.0","type":"link"}
