This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.\nSpecies Reactivity: Human\n\u003cb\u003eBackground\u003c\/b\u003e\nS100A8 and S100A9 are calcium-binding proteins that form a noncovalent heterodimer present in monocytes, neutrophils, macrophages, and some epithelial cells (1,2). S100A8 and S100A9 are secreted by a tubulin-dependent mechanism during inflammatory conditions and have antimicrobial and chemotactic functions (3-5). Extracellular S100A8\/S100A9 also induces an inflammatory response in endothelial cells, including induction of proinflammatory chemokines and adhesion molecules and increased vascular permeability (6). S100A8\/S100A9 induces and recruits myeloid-derived suppressor cells (MDSC) in tumor-bearing mice (7). MDSC produce additional S100A8\/S100A9 themselves, resulting in a positive feedback mechanism that sustains MDSC accumulation (7). S100A8\/S100A9 is also highly expressed in psoriatic skin, where it directly upregulates transcription of complement protein C3, which contributes to disease (8). In addition, tumor-infiltrating myeloid cells induce expression of S100A8 and S100A9 in cancer cells, which increases invasiveness and metastasis (9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n60B8AG; CAGB; calgranulin B; Calgranulin-B; Calprotectin L1H subunit; CFAG; CGLB; L1AG; Leukocyte L1 complex heavy chain; LIAG; MAC387; MIF; Migration inhibitory factor-related protein 14; MRP-14; MRP14; NIF; p14; Protein S100-A9; S100 calcium binding protein A9; S100 calcium-binding protein A9; S100 calcium-binding protein A9 (calgranulin B); S100A9; S10A9\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H","brand":"CST","offers":[{"title":"Default Title","offer_id":46800675766441,"sku":"80235V4","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-80235v4","provider":"Iright","version":"1.0","type":"link"}
