Rabbit Plasminogen activator inhibitor 1 (PAI-1) ELISA Kit#EK8673
评价
1-2周Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate PAI-1 in samples. An antibody specific for PAI-1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPAI-1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PAI-1 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 PAI-1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:Plasminogen activator inhibitor-1 is the principal inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA), the activators of plasminogen and hence fibrinolysis (the physiological breakdown of blood clots). It is a serine protease inhibitor (serpin) protein (SERPINE1). The other PAI, plasminogen activator inhibitor-2 (PAI-2) is secreted by the placenta and only present in significant amounts during pregnancy. In addition, protease nexin acts as an inhibitor of tPA and urokinase. PAI-1, however, is the main inhibitor of the plasminogen activators. PAI-1 is mainly produced by the endothelium (cells lining blood vessels), but is also secreted by other tissue types, such as adipose tissue.
