  • General notes

    Ablates APC binding to EPCR/CD201 thus blocking APC-mediated signalling.



Our Abpromise guarantee covers the use of ab81712 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Inhibition Assay Use a concentration of 10 - 25 µg/ml. Antibody RCR-252 functions as blocking antbody. It ablates APC binding to EPCR and blocks APC-mediated signaling.
Flow Cyt 1/50.

ab18407 - Rat monoclonal IgG1, is suitable for use as an isotype control with this antibody.


IP Use at an assay dependent concentration.
WB 1/50. Use under non reducing condition.


  • Function
    Binds activated protein C. Enhances protein C activation by the thrombin-thrombomodulin complex; plays a role in the protein C pathway controlling blood coagulation.
  • Tissue specificity
    Expressed strongly in the endothelial cells of arteries and veins in heart and lung, less intensely in capillaries in the lung and skin, and not at all in the endothelium of small vessels of the liver and kidney.
  • Post-translational
    A soluble form exists; probably released by a metalloprotease. Seems to have the same activity as the membrane-bound form.
