Product Information
KE00109 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The SERPINE1 ELISA kit is to be used to detect and quantify protein levels of endogenous SERPINE1. The assay recognizes human SERPINE1. An antibody specific for SERPINE1 has been pre-coated onto the microwells. The SERPINE1 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-conjugated antibody specific for SERPINE1 is added to detect the captured SERPINE1 protein. For signal development, 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
SERPINE1, also named as Plasminogen activator inhibitor type 1 (PAI-1), is a member of the serine protease inhibitor (SERPIN) superfamily. It is produced by the vascular endothelium, the liver, the monocytes/macrophagues, the platelets and the adipose tissue. High plasma levels of PAI-1 have been associated with an increased risk of suffering cardiovascular diseases. It is implicated in the pathogenesis of obesity, insulin resistance and type 2 diabetes. In several tumor types, SERPINE1 expression is up-regulated and it has been described as a poor prognostic marker. Besides its prognostic value, SERPINE1 expression has been validated as a marker for therapy decision making in patients with node-negative breast cancer. Defects in this gene are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1 deficiency), and high concentrations of the gene product are associated with thrombophilia.
