QC169 , Quantikine Immunoassay Control Set 839 Human Thrombomodulin -
The Quantikine Human Thrombomodulin Immunoassay is a 4.5 hour solid phase ELISA designed to measure human Thrombomodulin in cell culture supernates, cell lysates, serum, plasma, and urine. It contains NS0-expressed recombinant human Thrombomodulin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Thrombomodulin showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human Thrombomodulin.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision
The recovery of Thrombomodulin spiked to levels throughout the range of the assay was evaluated.

To assess the linearity of the assay, samples containing high concentrations of Thrombomodulin were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Thrombomodulin (TM), also known as CD141 and BDCA3, is a transmembrane expressed on vascular endothelial cells (EC), arterial smooth muscle cells, monocytes, and macrophages. It binds Thrombin and enhances the Thrombin-mediated activation of the anti-coagulant Protein C and the anti-fibrinolytic TAFI/Carboxypeptidase B2. Thrombomodulin also inhibits the ability of Thrombin to activate several pro-coagulant proteins (e.g. Fibrinogen, Factor V, Factor XIII, PAR-1). Thrombomodulin exerts multiple anti-inflammatory effects and reduces the severity of disease involving chronic inflammation. In cancer, Thrombomodulin suppresses tumor angiogenesis, growth, and epithelial-mesenchymal transition. Soluble fragments of Thrombomodulin are elevated in the serum, urine, and synovial fluid during coagulation disorders, inflammation, and organ failure.
Refer to the product for complete assay procedure.
Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
Prepare all reagents, standard dilutions, and samples as directed in the product insert.
Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
