The receptors are designated CXCR1-5, CCR1-11, XCR1 and CX3CR1, based on their specific ligand preference2.Chemokine receptors are present on many different cell types. They were initially detected on leukocytes, where they were found to play an important role in the migration of these cells to inflammation sites3.CXCR4 was originally identified as an orphan receptor, and soon gained much attention when it was discovered as a coreceptor for HIV-14.\u003c\/p\u003e  \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eProfiling immune-marker expression across cell subsets with single-cell or flow-based readouts.\u003c\/li\u003e   \u003cli\u003eConnecting receptor\/ligand levels to activation state and cytokine programs.\u003c\/li\u003e   \u003cli\u003eApplying genetic perturbation or orthogonal assays to support specificity and interpretation.\u003c\/li\u003e \u003c\/ul\u003e  \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eFlow cytometry (direct\/indirect): quantify target-positive populations and shifts in expression across subsets.\u003c\/li\u003e   \u003cli\u003eLive cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.\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: RIC-001-F.\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-CR014; Negative control: RIC-001-F.\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":"15 mcl \/ 1","offer_id":53064823112045,"sku":"ACR-014-F-15MCL-1","price":597.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 1","offer_id":53064882028909,"sku":"ACR-014-F-50MCL-1","price":797.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 2","offer_id":53064882061677,"sku":"ACR-014-F-50MCL-2","price":1397.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 5","offer_id":53064882094445,"sku":"ACR-014-F-50MCL-5","price":2743.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 10","offer_id":53064882127213,"sku":"ACR-014-F-50MCL-10","price":3764.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/ACR-014-FC1.png?v=1772460950","url":"https:\/\/www.ebiohippo.com\/products\/anti-cxcr4-extracellular-fitc-antibody-bha21300251","provider":"BioHippo","version":"1.0","type":"link"}
