{"product_id":"v7646-20ug","title":"Occludin Antibody","description":"\u003cp\u003eOccludin is a tetraspan integral membrane protein in epithelial and endothelial tight junction (TJ) structures that can contain two extracellular loops. The protein exists in a variety of phosphorylated forms. Phosphorylation is involved in regulating both the localization and the function of Occludin. Expression of Occludin is upregulated by polyunsaturated fatty acids, increasing trans-endothelial cell resistance and reducing cellular permeability to large molecules. The level of Occludin varies greatly depending on tissue; in brain tissue, Occludin is highly expressed at cell-cell contact sites. Non-neural tissues show lower expression and discontinuous distribution. Up-regulation of epithelial Occludin may play a role in enhancing paracellular permeability and be related to the damage to the tight junction.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug \/ Mouse","offer_id":49431189913880,"sku":"V7646-20UG","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_a967f5a1-9217-4c62-9c08-f8eea090893b.jpg?v=1733339993","url":"https:\/\/danabiosci.com\/products\/v7646-20ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
