This gene is a member of the Ets family of transcription factors and of the ternary complex factor (TCF) subfamily. Proteins of the TCF subfamily form a ternary complex by binding to the the serum response factor and the serum response element in the promoter of the c-fos proto-oncogene. The protein encoded by this gene is a nuclear target for the ras-raf-MAPK signaling cascade. This gene produces multiple isoforms by using alternative translational start codons and by alternative splicing. Related pseudogenes have been identified on chromosomes 7 and 14.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCross reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eQuantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.\u003c\/li\u003e \u003cli\u003eIsoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.\u003c\/li\u003e \u003cli\u003eContext-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blot (WB):\u003c\/strong\u003e compare relative target abundance and apparent size shifts (e.g., isoforms\/PTMs) across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e assess distribution across tissue compartments and compare staining patterns between groups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and compare shifts after stimulation or differentiation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAcross these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eApparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.\u003c\/li\u003e \u003cli\u003eSpecies reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.\u003c\/li\u003e \u003cli\u003eControl concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO\/KD, peptide competition, or independent assays) to support interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eFor antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.\u003c\/p\u003e \u003c!-- Sources (internal): - UniProt entry for ELK1 (P19419) — UniProt Consortium — https:\/\/www.uniprot.org\/uniprotkb\/P19419 - Ensembl gene summary for ELK1 — Ensembl — https:\/\/www.ensembl.org - HGNC gene symbol report for ELK1 — HGNC — https:\/\/www.genenames.org - Antibody validation concepts (general) — NIH\/NCBI resources — https:\/\/www.ncbi.nlm.nih.gov --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53068595888493,"sku":"A01426-1","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53068779290989,"sku":"A01426-1-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53068779323757,"sku":"A01426-1-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53068779356525,"sku":"A01426-1-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53068779389293,"sku":"A01426-1-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53068779422061,"sku":"A01426-1-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53068779454829,"sku":"A01426-1-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53068779487597,"sku":"A01426-1-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53068779520365,"sku":"A01426-1-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53068779553133,"sku":"A01426-1-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53068779585901,"sku":"A01426-1-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53068779618669,"sku":"A01426-1-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/a01426-1-elk1-primary-antibodies-wb-testing-1.jpg?v=1772611290","url":"https:\/\/www.ebiohippo.com\/products\/anti-elk1-antibody-picoband-bha21004327","provider":"BioHippo","version":"1.0","type":"link"}
