Thrombomodulin, BioAssay(TM) ELISA Kit (Mouse)

Thrombomodulin(TM), CD141 or BDCA-3 is an integral membrane protein expressed on the surface of endothelial cells and serves as a cofactor for thrombin. It reduces blood coagulation by converting thrombin to an anticoagulant enzyme from a procoagulant enzyme. Thrombomodulin is also expressed on human mesothelial cell, monocyte and a dendritic cell subset. In humans, thrombomodulin is encoded by the THBD gene. The protein has a molecular mass of 74kDa, and consists of a single chain with 5 distinct domains. Thrombomodulin functions as a cofactor in the thrombin-induced activation of protein C in the anticoagulant pathway by forming a 1:1 stoichiometric complex with thrombin. This raises the speed of protein C activation thousandfold. Thrombomodulin-bound thrombin has procoagulant effect at the same time by inhibiting fibrinolysis by cleaving thrombin-activatable fibrinolysis inhibitor(TAFI,aka carboxypeptidase B2) into its active form. Thrombomodulin is a glycoprotein on the surface of endothelial cells that, in addition to binding thrombin, regulates C3b inactivation by factor I. Mutations in the thrombomodulin gene(THBD) have also been reported to be associated with atypical hemolytic-uremic syndrome(aHUS). Sample Type: Cell culture supernates, serum, plasma (heparin, EDTA, citrate) and urine. Intended Use: For quantitative detection of mouse Thrombomodulin in cell culture supernates, serum, plasma (heparin, EDTA, citrate) and urine. Sensitivity: <10pg/ml, Range: 62.5-4000pg/ml, Specificity: Natural and recombinant mouse Thrombomodulin, Test Principle: This mouse Thrombomodulin BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for Thrombomodulin has been precoated onto 96-well plates. Standards(NSO) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Thrombomodulin is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse Thrombomodulin amount of sample captured in plate.
