描述	Human sE-Selectin-1 ELISA
概述	E-selectin (Endothelial Leukocyte Adhesion Molecule-1, ELAM-1) belongs to the selectin family of adhesion molecules [Hogg, 1992; Lasky, 1991]. Together with LECAM-1 (L-selectin) and GMP-140 (P-selectin), E-selectin mediates the initial interactions of leukocytes and platelets with endothelial cells [Shimizu et al., 1991; Vonandrian et al., 1992]. Molecular structure: The extracellular part of all selectins consists of an aminoterminal c-type lectin domain which specifically binds to carbohydrate ligands. This is followed by an EGF-like domain, and, in the case of E-selectin, by 6 short consensus repeats. The transmembrane portion of the molecule is followed by a short cytoplasmic tail. Selectins provide the first, loose contacts of polymorphonuclear cells with the endothelium in areas of inflammation. The binding partner for E-selectin contains sialyl LewisX oligosaccharide or lactosaminoglycans that contain either sialic acid or fucose [Foxall, et al., 1992; Parekh, 1991]. E-selectin is expressed on cytokine-activated endothelial cells, and promotes the adhesion of leukocytes to the endothelium. This initial binding event is a prerequisite for the activation of the immune cells via inflammatory mediators [Kyan-Aung et al., 1991; Lawrence & Springer, 1991]. In contrast to GMP-140, E-selectin is maximally expressed 2-4 hours after cell activation. During the following 24-48 hours E-selectin is shed from the cytoplasmic membrane into the circulation [Pigott et al., 1992]. The circulating form of this selectin attracts neutrophils and activates the b2-integrins in preparing the cells for migration. Soluble E-selectin levels could provide insights into several pathologies, including allergic reactions [Brasch & Sterry, 1992; Gundel et al., 1991; Mulligan et al., 1991], septic shock [Engelberts et al., 1992; Munro et al., 1991; Redl et al., 1991], vascular infection and inflammatory bowel disease [Koizumi et al., 1992]. Test Principle: An anti-E-selectin monoclonal antibody is adsorbed onto microwells. The pair of monoclonal antibodies used in this ELISA detect the soluble form of E-Selectin present in serum, plasma, urine, and other biological fluids. Soluble E-selectin present in a sample or standard then binds to antibodies adsorbed to the microwells. A second, HRP-conjugated monoclonal anti-E-selectin antibody is added and binds to E-selectin captured by the first antibody. Unbound enzyme-conjugated anti-E-selectin is removed with a wash step and HRP substrate solution is added to the wells. An amount of colored product is formed, proportional to the amount of soluble E-selectin present in the sample. The reaction is terminated by addition of acid and absorbance is measured at 450nm. A standard curve is prepared from six E-selectin standard dilutions and the E-selectin sample concentration is determined. Application: The E-selectin ELISA is an enzyme-linked immunosorbent assay for the quantitative detection of soluble Endothelial Leukocyte Adhesion Molecule-1 levels in cell culture supernatants, human serum, plasma, amniotic fluid, or other body fluids. The E-selectin ELISA is for research use only. Not for use in diagnostic or therapeutic procedures.

可用的分析物	sE-Selectin-1
Entrez基因编号	NM_000450.1
Entrez基因汇总	The endothelial leukocyte adhesion molecule-1 is expressed by cytokine-stimulated endothelial cells. It is thought to be responsible for the accumulation of blood leukocytes at sites of inflammation by mediating the adhesion of cells to the vascular lining. It exhibits structural features such as the presence of lectin- and EGF-like domains followed by short consensus repeat (SCR) domains that contain 6 conserved cysteine residues. These proteins are part of the selectin family of cell adhesion molecules. This gene is present in single copy in the human genome and contains 14 exons spanning about 13 kb of DNA. Adhesion molecules participate in the interaction between leukocytes and the endothelium and appear to be involved in the pathogenesis of atherosclerosis.
