Tissue factor (TF)

Links to databases


Tissue factor (TF) is the cell surface receptor for the serine protease factor VIIa. The best known function of TF is its role in blood coagulation. The complex of TF with factor VIIa catalyzes the conversion of the inactive protease factor X into the active protease factor Xa. TF is expressed by cells which are normally not exposed to flowing blood such as smooth muscle cells and cells surrounding blood vessels (e.g. fibroblasts). This can change when the blood vessel is damaged by physical injury or rupture of atherosclerotic plaques.

Tissue factor (TF)


    • Within run precision Coefficient of Variation (CV)
    • 8%
    • Between run precision Coefficient of Variation (CV)
    • 13%

Precision (repeatability) is calculated from linearized NPX values over LOD.
