LEP-R forms a high-affinity 1:1 ratio complex with leptin in solution, but does not form the 2:1 ratio complex associated with the small cytokine receptors, such as growth hormone receptor (GHR). The 1:1 ratio interaction occurs at leptin's binding site II and can be blocked by mutations in this region.\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\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   \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: BLP-LR039.\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-LR039; Negative control: BLP-LR039.\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":53064834154861,"sku":"ALR-039-CF-0P2ML-1","price":994.0,"currency_code":"USD","in_stock":true},{"title":"0.2 ml \/ 1","offer_id":53064914010477,"sku":"ALR-039-0P2ML-1","price":795.0,"currency_code":"USD","in_stock":true},{"title":"25 mcl \/ 1","offer_id":53064914043245,"sku":"ALR-039-25MCL-1","price":597.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 1","offer_id":53064914076013,"sku":"ALR-039-50MCL-1","price":697.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/ALR-039-EPT_a05d7952-446b-4638-a73c-bfbb75b6e3e7.png?v=1772461000","url":"https:\/\/www.ebiohippo.com\/products\/anti-leptin-receptor-extracellular-antibody-bha21300590","provider":"BioHippo","version":"1.0","type":"link"}
