Human Thrombomodulin/BDCA-3 Quantikine ELISA Kit Summary

Product Summary

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.

Preparation and Storage

Background: Thrombomodulin/BDCA-3

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.

Assay Procedure

Refer to the product datasheet for the 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.

1、Prepare all reagents, standard dilutions, and samples as directed in the product insert.

2、Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

3、Add 50 μL of Assay Diluent to each well.

4、Add 50 μL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.

5、Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

6、Add 100 μL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.

7、Aspirate and wash 5 times.

8、Add 100 μL Substrate Solution to each well.

9、Add 100 μL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
