Maximum absorption 629 nm; maximum fluorescence 657 nm. The fluorescence is excited most efficiently in the 610 - 645 nm range. This label is analogous to the dyes Alexa 647, Alexa 633 and Cy5 and can be used for direct flow cytometry (FACS) using the He:Ne laser.). This antibody is commonly used in FC, LCI to detect, localize, or compare expression of the target across samples.\u003c\/p\u003e  \u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003e\n\u003cstrong\u003eTarget:\u003c\/strong\u003e TMEM142A, CRACM1, Calcium release-activated calcium channel protein 1 (also reported as TMEM142A, CRACM1, Calcium release-activated calcium channel protein 1).\u003c\/li\u003e   \u003cli\u003e\n\u003cstrong\u003eImmunogen\/epitope region:\u003c\/strong\u003e Extracellular.\u003c\/li\u003e   \u003cli\u003e\n\u003cstrong\u003eHomology note:\u003c\/strong\u003e Recognizes Orai1 from human samples only (informative for cross-species interpretation).\u003c\/li\u003e   \u003cli\u003e\n\u003cstrong\u003eSpecies reactivity (as provided):\u003c\/strong\u003e Human.\u003c\/li\u003e   \u003cli\u003e\n\u003cstrong\u003eSpecificity statement (as provided):\u003c\/strong\u003e Recognizes only human Orai1..\u003c\/li\u003e   \u003cli\u003e\n\u003cstrong\u003eCited use:\u003c\/strong\u003e FC (literature use does not guarantee performance in every setup).\u003c\/li\u003e   \u003cli\u003e\n\u003cstrong\u003eLot quality control (as provided):\u003c\/strong\u003e Western blot analysis (unlabeled antibody, #ALM-025), and direct flow cytometry (labeled antibody)..\u003c\/li\u003e   \u003cli\u003e\n\u003cstrong\u003ePeptide confirmation:\u003c\/strong\u003e Confirmed by amino acid analysis and mass spectrometry.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eThese attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.\u003c\/p\u003e  \u003ch2\u003eBiological background\u003c\/h2\u003e \u003cp\u003eCytosolic calcium (Ca2+) has long been known to act as a key second messenger in many intracellular pathways including synaptic transmission, muscle contraction, hormonal secretion, cell growth and proliferation.1,2 The mechanism controlling intracellular Ca2+ level influx either by the calcium-release-activated Ca2+ channels (CRAC), or from intracellular stores, has become of great interest.Recently, several key players of the store operated complex have been identified3. Orai1 (also known as CRACM1) acts as the store operated Ca2+ channel (SOC) and STIM1, which acts as the endoplasmic reticulum Ca2+ sensor3,4. The formation of functional channels requires the presence of both Orai1 and STIM1 proteins working as a complex and involves the co-clustering of Orai1 on the plasma membrane with STIM1 on the endoplasmic reticulum4-6.\u003c\/p\u003e  \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eLinking transporter\/channel abundance to ionic homeostasis and excitability-related phenotypes.\u003c\/li\u003e   \u003cli\u003eStudying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.\u003c\/li\u003e   \u003cli\u003eCombining antibody readouts with functional assays for more complete 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\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 \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":"50 mcg \/ 1","offer_id":53064833302893,"sku":"ALM-025-FR-50MCG-1","price":797.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/ALM-025-FR_gr.gif?v=1772460997","url":"https:\/\/www.ebiohippo.com\/products\/mouse-anti-human-orai1-extracellular-atto-fluor-633-antibody-bha21300568","provider":"BioHippo","version":"1.0","type":"link"}
