It belongs to the rhodopsin-like subfamily of class A transmembrane spanning (7TM) G protein-coupled receptors and its most potent ligand is oxysterol 7α-25-OHC 1.Dihydroxycholesterols, such as oxysterol 7α-25-OHC, are generated from cholesterol in steady state but also in the context of inflammation. GPR183 senses these oxysterols and induces chemotactic migration of immune cells towards higher concentrations of these ligands and hence cells that express GPR183 are trafficking through an oxysterol gradient dependent manner acting like chemokine processes.\u003c\/p\u003e  \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eComparing host-factor expression across tissues, disease models, and perturbations.\u003c\/li\u003e   \u003cli\u003eAssessing receptor availability and localization as a proxy for entry-related biology (context-dependent).\u003c\/li\u003e   \u003cli\u003eUsing tissue-context methods (IHC\/IF) to relate expression to pathology and cell-type composition.\u003c\/li\u003e \u003c\/ul\u003e  \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eWestern blot (WB): compare target abundance\/size across lysates and conditions; consider isoforms\/PTMs.\u003c\/li\u003e   \u003cli\u003eImmunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.\u003c\/li\u003e   \u003cli\u003eImmunofluorescence\/ICC: assess subcellular localization and co-localization with markers in cells or sections.\u003c\/li\u003e   \u003cli\u003eFlow cytometry (direct\/indirect): quantify target-positive populations and shifts in expression across subsets.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eInterpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO\/KD) and using orthogonal readouts where feasible.\u003c\/p\u003e  \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eIsoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.\u003c\/li\u003e   \u003cli\u003eCross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.\u003c\/li\u003e   \u003cli\u003ePermeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.\u003c\/li\u003e   \u003cli\u003eConceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.\u003c\/li\u003e   \u003cli\u003eProvided control suggestions: Negative control: BLP-GR063.\u003c\/li\u003e   \u003cli\u003eApplication notes: see product-specific dilution\/usage notes and control concepts provided in the dataset.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eApplication abbreviations:\u003c\/strong\u003e CBE- Cell-based ELISA, FC- Flow cytometry, ICC- Immunocytochemistry, IE- Indirect ELISA, IF- Immunofluorescence, IFC- Indirect flow cytometry, IHC- Immunohistochemistry, IP- Immunoprecipitation, LCI- Live cell imaging, N- Neutralization, WB- Western blot. \u003cstrong\u003eSpecies abbreviations:\u003c\/strong\u003e H- Human, M- Mouse, R- Rat.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eRecommended controls:\u003c\/strong\u003e Blocking peptide: BLP-GR063; Negative control: BLP-GR063.\u003c\/p\u003e \u003c!-- Sources (internal): - Alomone Labs product page scientific background (as provided in this catalog row) - UniProt Knowledgebase (target-level reference) - NCBI Gene (target-level reference) - General antibody validation principles (KO\/KD, peptide competition, isotype control concepts) --\u003e","brand":"Alomone Labs","offers":[{"title":"0.2 ml (Carrier Free) \/ 1","offer_id":53064830615917,"sku":"AGR-063-CF-0P2ML-1","price":994.0,"currency_code":"USD","in_stock":true},{"title":"0.2 ml \/ 1","offer_id":53064904966509,"sku":"AGR-063-0P2ML-1","price":795.0,"currency_code":"USD","in_stock":true},{"title":"25 mcl \/ 1","offer_id":53064904999277,"sku":"AGR-063-25MCL-1","price":597.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 1","offer_id":53064905032045,"sku":"AGR-063-50MCL-1","price":697.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/AGR-063_ept-1-300x165.png?v=1772460987","url":"https:\/\/www.ebiohippo.com\/products\/anti-gpr183-extracellular-antibody-bha21300484","provider":"BioHippo","version":"1.0","type":"link"}
