Product Information
KE00205 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Pentraxin 3/TSG-14 ELISA kit is to be used to detect and quantify protein levels of endogenous Pentraxin 3/TSG-14. The assay recognizes human Pentraxin 3/TSG-14. An antibody specific for Pentraxin 3/TSG-14 has been pre-coated onto the microwells. The Pentraxin 3/TSG-14 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for human Pentraxin 3/TSG-14 is added to detect the captured human Pentraxin 3/TSG-14 protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
Pentraxin 3 (PTX3), also known as TNF-inducible gene 14 protein (TSG-14), is a member of the pentraxin superfamily which consists of evolutionarily conserved proteins characterized by a structural motif, the pentraxin domain. Pentraxin 3 can be produced by a variety of cell types including endothelial cells, smooth muscle cells, adipocytes, fibroblasts, mononuclear phagocytes, and dendritic cells, and its expression is induced by primary inflammatory signals, such as IL-1, TNF, and microbial moieties. Pentraxin 3 is an acute phase glycoprotein that plays a role in the regulation of innate resistance to pathogens, inflammation, tissue remodeling and repair, female fertility and cancer. Pentraxin 3 is a biomarker for cardiovascular disease. Increased plasma Pentraxin 3 levels have been found in patients with cardiovascular disorders.
