NPS expression is limited to a few discrete brain areas, such as in isolated cells of the amygdala, the hypothalamus, and specific regions of the brainstem. The primary sequence of NPS is highly conserved among vertebrates especially at the N-terminus, which is crucial for biological activity.\u003c\/p\u003e  \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eComparing target expression across perturbations, genotypes, or treatment conditions.\u003c\/li\u003e   \u003cli\u003eInterpreting localization shifts alongside pathway or phenotypic readouts.\u003c\/li\u003e   \u003cli\u003eUsing orthogonal controls (KO\/KD, peptide competition, isotype concepts) to support conclusions.\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-NR029.\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-NR029; Negative control: BLP-NR029.\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":53064838087021,"sku":"ANR-029-CF-0P2ML-1","price":994.0,"currency_code":"USD","in_stock":true},{"title":"0.2 ml \/ 1","offer_id":53064922825069,"sku":"ANR-029-0P2ML-1","price":795.0,"currency_code":"USD","in_stock":true},{"title":"25 mcl \/ 1","offer_id":53064922857837,"sku":"ANR-029-25MCL-1","price":597.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 1","offer_id":53064922890605,"sku":"ANR-029-50MCL-1","price":697.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/ANR-029_ept_5aa15f98-b626-471f-8c1c-72a11a4a2786.png?v=1772461015","url":"https:\/\/www.ebiohippo.com\/products\/anti-neuropeptide-s-receptor-extracellular-antibody-bha21300693","provider":"BioHippo","version":"1.0","type":"link"}
