The UniProt recommended name is Pancreatic and duodenal homeobox 1 (PDX1). This nuclear protein functions as a master regulator of pancreatic organogenesis and endocrine function, orchestrating the transcriptional networks that specify pancreatic progenitor cells and maintain mature beta-cell identity.\u003cbr\u003e\u003cbr\u003eFunctionally, PDX1 antibody identifies a 283-amino-acid homeodomain-containing protein that binds to promoter regions of multiple pancreatic genes, including insulin, somatostatin, glucokinase, and GLUT2. PDX1 interacts with transcriptional cofactors such as PBX1, NEUROD1, and MAFA to activate insulin transcription and coordinate glucose-stimulated insulin secretion. During embryogenesis, PDX1 marks multipotent progenitors in the foregut endoderm that give rise to all pancreatic cell lineages.\u003cbr\u003e\u003cbr\u003eThe PDX1 gene is located on chromosome 13q12.2 and is highly expressed in the pancreas, particularly in beta cells of the islets of Langerhans and in the duodenal epithelium. PDX1 expression is regulated by glucose, nutrient status, and signaling pathways including PI3K\/AKT and MAPK. Its activity ensures proper glucose homeostasis and metabolic regulation.\u003cbr\u003e\u003cbr\u003ePathologically, mutations in PDX1 cause pancreatic agenesis, maturity-onset diabetes of the young type 4 (MODY4), and contribute to type 2 diabetes through impaired beta-cell function. Loss of PDX1 expression leads to beta-cell dedifferentiation, while overexpression can promote transdifferentiation of non-beta pancreatic cells into insulin-producing phenotypes. Research using PDX1 antibody supports studies in diabetes, pancreatic development, and regenerative medicine.\u003cbr\u003e\u003cbr\u003ePDX1 antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect transcription factors involved in endocrine development. \u003cbr\u003e\u003cbr\u003eStructurally, Pancreatic and duodenal homeobox 1 contains a highly conserved homeobox domain responsible for DNA binding and nuclear localization signals that target it to the nucleus. Post-translational modifications such as phosphorylation modulate PDX1 stability and transcriptional activity. This antibody enables investigation of PDX1's role in pancreatic morphogenesis, beta-cell identity maintenance, and metabolic gene regulation.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence:\u003c\/strong\u003e visualize subcellular distribution and cell-to-cell heterogeneity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=PDX1 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=PDX1 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=PDX1 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/PDX1 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=PDX1+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047318675821,"sku":"FY13210","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_125c6a9d-d29c-4a8f-8dd2-d731c11ade8f.jpg?v=1782237074","url":"https:\/\/www.ebiohippo.com\/products\/pdx1-antibody-pancreatic-and-duodenal-homeobox-1-bha17136112","provider":"BioHippo","version":"1.0","type":"link"}
