Occludin is a 59 kDa tetraspan protein localized at intercellular junctions of epithelial and endothelial cells. It works together with claudins, junctional adhesion molecules (JAMs), and cytoplasmic scaffolding proteins such as ZO-1 to form the tight junction complex that regulates paracellular permeability. The OCLN antibody enables specific detection of Occludin, allowing researchers to investigate the molecular architecture of tight junctions and how their disruption contributes to disease.\u003cbr\u003e\u003cbr\u003eOccludin plays a central role in maintaining cell polarity, barrier selectivity, and communication between adjacent cells. It acts as both a structural and signaling molecule, participating in pathways that control cell growth and differentiation. Phosphorylation of Occludin on serine, threonine, or tyrosine residues dynamically regulates its interaction with cytoplasmic partners and influences tight junction assembly and disassembly. The OCLN antibody is an essential reagent for tracking these modifications and monitoring Occludin redistribution during epithelial remodeling or inflammation.\u003cbr\u003e\u003cbr\u003eMutations in OCLN cause band-like calcification with simplified gyration and polymicrogyria (BLC-PMG), a neurological disorder associated with cortical malformations and hepatic dysfunction. These findings underscore the systemic importance of Occludin beyond epithelial physiology. The OCLN antibody provides researchers with a means to quantify protein levels in both brain and peripheral tissues, aiding studies into developmental and metabolic roles of tight junction components.\u003cbr\u003e\u003cbr\u003eOccludin dysfunction is also implicated in a range of diseases, including cancer metastasis, viral infection, and inflammatory bowel disease. Pathogens such as hepatitis C virus and cytomegalovirus exploit Occludin to gain cellular entry or modulate junction integrity. Altered Occludin expression can weaken epithelial barriers, promoting invasion or chronic inflammation. The OCLN antibody allows visualization of these alterations in tissue models, helping elucidate how tight junction disruption contributes to pathogenesis.\u003cbr\u003e\u003cbr\u003eThe OCLN antibody performs effectively in immunofluorescence microscopy, immunohistochemistry, and western blotting. In epithelial cultures, staining reveals tight junction localization, while in tissues it highlights barrier organization across endothelium and epithelia.\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\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\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=OCLN - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=OCLN - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=OCLN - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/OCLN - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=OCLN+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":53047285186925,"sku":"FY12345","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_5d85457f-5f13-41c7-8ad2-dda881ac1b15.jpg?v=1782236988","url":"https:\/\/www.ebiohippo.com\/products\/ocln-antibody-occludin-bha17135248","provider":"BioHippo","version":"1.0","type":"link"}
