The Ca2+ permeability is dependent on the presence of AMPA21.Gating of AMPA receptors by glutamate is extremely fast and therefore the AMPA receptors mediate most excitatory (depolarizing) currents in the brain during basal neuronal activity. The depolarization caused by the activation of post-synaptic AMPA receptors is necessary for the activation of NMDA receptors that will open only in the presence of both glutamate and a depolarized membrane potential.Synaptic strength that is defined as the level of post-synaptic depolarization can be long term (hence the term long term potentiation, LTP) and therefore induce changes in signaling and protein synthesis in the activated neuron.\u003c\/p\u003e  \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eMapping receptor\/channel localization across neuronal subtypes and subcellular compartments.\u003c\/li\u003e   \u003cli\u003eLinking trafficking or surface expression changes to activity-dependent signaling and plasticity.\u003c\/li\u003e   \u003cli\u003eUsing KO\/KD or blocking-peptide concepts to strengthen antibody-based target assignment.\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 \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-GC010.\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-GC010; Negative control: BLP-GC010.\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":53064827765101,"sku":"AGC-010-GP-CF-0P2ML-1","price":994.0,"currency_code":"USD","in_stock":true},{"title":"0.2 ml \/ 1","offer_id":53064895103341,"sku":"AGC-010-GP-0P2ML-1","price":795.0,"currency_code":"USD","in_stock":true},{"title":"25 mcl \/ 1","offer_id":53064895136109,"sku":"AGC-010-GP-25MCL-1","price":597.0,"currency_code":"USD","in_stock":true},{"title":"50 mcl \/ 1","offer_id":53064895168877,"sku":"AGC-010-GP-50MCL-1","price":697.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/AGC-010.gif?v=1772460973","url":"https:\/\/www.ebiohippo.com\/products\/guinea-pig-anti-glur3-glua3-extracellular-antibody-bha21300395","provider":"BioHippo","version":"1.0","type":"link"}
