Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate EDIL3 in samples. An antibody specific for EDIL3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyEDIL3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for EDIL3 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of EDIL3 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:EDIL3 is a glycoprotein that is secreted by endothelial cells and can associate with the endothelial cell surface and the extracellular matrix. EDIL3 is regulated by hypoxia or vascular injury and has been implicated in vascular remodeling during angiogenesis.The predicted 480-amino acid mouse and human proteins, which are 95% identical, contain a signal peptide, 3 epidermal growth factor (EGF)-like repeats, and 2 discoidin I-like repeats. Northern blot analysis revealed expression of a 6.5-kb transcript in highly vascularized mouse embryonic day-15.5 tissue and in mouse and human endothelial cells, but not in other adult tissues. In situ hybridization analysis showed Del1 expression in developing endocardium at 9.5 days postcoitus and in renal artery and hypertrophic chondrocytes at 13.5 days postcoitus.
