Product Summary for Human EPCR Quantikine ELISA Kit

The Quantikine Human EPCR Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human EPCR in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant human EPCR and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human EPCR 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 EPCR.

Background: EPCR

EPCR (the Endothelial Protein C Receptor), also known as CD201, is a transmembrane glyoprotein expressed on vascular endothelial cells. EPCR inhibits thrombosis through its interactions with Protein C, activated Protein C (APC), and Coagulation Factors VII, and VIIa. It enhances the activation of Protein C in response to complexes of Thrombin-Thrombomodulin. A soluble form of EPCR inhibits the anti-coagulant activity of APC. EPCR binds to CD11b/CD18 (Mac-1) on monocytes and mediates monocyte adhesion to the vascular endothelium. In addition, it binds to the antigen receptor on gamma/delta T cells, promotes hematopoietic stem cell retention in the bone marrow, and contributes to malaria pathogenicity through binding surface proteins on Plasmodium.
