SIGLEC1 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 Sus scrofa (Pig) 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\u003eProfiling immune signaling nodes and cytokine pathways across cell types and activation states.\u003c\/li\u003e \u003cli\u003eStudying ligand–receptor interactions that shape immune cell communication and effector function.\u003c\/li\u003e \u003cli\u003eBuilding quantitative assays to compare pathway modulation by genetic or pharmacologic perturbations.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Macrophage-restricted adhesion molecule that mediates sialic-acid dependent binding to lymphocytes, including granulocytes, monocytes, natural killer cells, B-cells and CD8 T-cells. Preferentially binds to alpha-2,3-linked sialic acid. Binds to SPN\/CD43 on T-cells. May play a role in hemopoiesis (By similarity). Acts as an endocytic receptor mediating clathrin dependent endocytosis. In case of porcine reproductive and respiratory syndrome virus (PRRSV), mediates virion attachment and internalization into alveolar macrophages through a clathrin-coated dependent process.\u003c\/p\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 A7LCJ3 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/A7LCJ3\/entry - NCBI Gene search (SIGLEC1) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=SIGLEC1 - PubMed search (SIGLEC1) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=SIGLEC1 - RCSB PDB search (SIGLEC1) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=SIGLEC1 - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065271247213,"sku":"CSB-EP021293PI-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065386099053,"sku":"CSB-EP021293PI-100UG","price":729.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065386131821,"sku":"CSB-EP021293PI-20UG","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP021293PI-SDS.jpg?v=1772476400","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-pig-sialoadhesin-siglec1-partial-bhp10508866","provider":"BioHippo","version":"1.0","type":"link"}
