A monoclonal antibody from mouse specific for Periostin\/OSF2 has been pre-coated onto 96-well plates. Standards (Expression system for standard: NSO; Immunogen sequence: N22-Q836) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Periostin\/OSF2 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Human Periostin\/OSF2 amount of sample captured in plate.\u003cbr\u003e\nPeriostin, also known as OSF2, is a protein that in humans is encoded by the POSTN gene. The International Radiation Hybrid Mapping Consortium mapped the POSTN gene to chromosome 13. Periostin functions as a ligand for alpha-V\/beta-3 and alpha-V\/beta-5 integrins to support adhesion and migration of epithelial cells. It is found that periostin was over-expressed by the majority of human primary breast cancers examined. After myocardial infarction, periostin-induced cardiomyocyte cell cycle reentry and mitosis were associated with improved ventricular remodeling and myocardial function, reduced fibrosis and infarct size, and increase angiogenesis.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions--20°C, Appropriate long-term storage conditions--20°C, Storage information--20°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nPeriostin also known as POSTN or OSF-2 is an extracellular matrix protein with a molecular weight of approximately 90 kDa. It plays a mechanical role in tissue remodeling by binding to integrins which supports tissue repair and regeneration. Periostin is mainly expressed in collagen-rich tissues such as bone periodontal ligament and cardiac tissues. It is synthesized by osteoblasts fibroblasts and other stromal cells functioning as a structural protein that supports cell adhesion and migration.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe periostin protein contributes to the maintenance of tissue integrity and mechanical properties. It does not solely act; it forms part of a multiprotein complex with collagen and other extracellular matrix components. This involvement is necessary for maintaining cellular interactions and promoting tissue healing processes. Additionally periostin influences cell proliferation and migration impacting developmental and wound healing biology.\u003cbr\u003e\nPathways\u003cbr\u003e\nPeriostin is involved in the integrin signaling pathway and the Wnt\/β-catenin pathway both important for cell communication and movement. Through these pathways periostin interacts with integrins αvβ3 and αvβ5 facilitating cell adhesion and migration. The Wnt\/β-catenin pathway interaction involves several proteins including Frizzled receptors ensuring regulation of cellular proliferation and differentiation. These pathways make periostin a coordinator of complex cellular processes.\u003cbr\u003e\nThe periostin protein is associated with conditions such as fibrotic diseases and cardiovascular disorders. In fibrosis periostin promotes collagen cross-linking exacerbating tissue stiffness. This involves increased interaction with proteins like collagen types I and V contributing to pathological fibrotic progression. In cardiovascular disorders elevated periostin levels after myocardial injury are linked with fibrotic scarring where it collaborates with matrix metalloproteinases to remodel the cardiac tissue architecture. Understanding these connections can lead to novel therapeutic strategies.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843645362345,"sku":"ab213816","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab213816","provider":"Iright","version":"1.0","type":"link"}
