Ephrins can be divided into two subclasses: ephrin A and ephrin B. Ephrin A ligands (ephrin A1-A5) are anchored to the cell surface via a glycosylphosphatidylinositol (GPI) anchor and bind to Eph A receptors (Eph A1-A8), whereas ephrin B ligands (ephrin B1-B3) have transmembrane and cytoplasmic domains and interact with Eph B receptors (Eph B1-B6)2.Eph receptors and ephrins are highly expressed in the brain and in the developing nervous system, where they have well-known roles in the establishment of neuronal connectivity by guiding axons to the appropriate targets and regulating the formation of synaptic connections.\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\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-ER031.\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-ER031; Negative control: BLP-ER031.\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":53064825536877,"sku":"AER-031-CF-0P2ML-1","price":994.0,"currency_code":"USD","in_stock":true},{"title":"0.2 ml \/ 1","offer_id":53064888582509,"sku":"AER-031-0P2ML-1","price":795.0,"currency_code":"USD","in_stock":true},{"title":"25 mcl \/ 1","offer_id":53064888615277,"sku":"AER-031-25MCL-1","price":597.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 1","offer_id":53064888648045,"sku":"AER-031-50MCL-1","price":697.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/AER-031_ept.gif?v=1772460969","url":"https:\/\/www.ebiohippo.com\/products\/anti-ephrin-a1-extracellular-antibody-bha21300319","provider":"BioHippo","version":"1.0","type":"link"}
