Background: Coagulation Factor VII
Coagulation Factors VII and VIIa refer to the pro and active forms of the same protease, respectively (1). Factor VII is synthesized in the liver and circulates in the plasma where it binds to tissue factor (TF), an integral membrane protein found in a variety of cell types. Upon binding of TF, Factor VII is rapidly converted into VIIa. The resulting 1:1 complex of VIIa and TF initiates the coagulation pathway and has also important coagulation-independent functions such as angiognesis (2). The cleavage and activation of Coagulation Factors VII, IX and X by VIIa:TF is phospholipid-dependent whereas the cleavage of small peptide substrates is not (1). The predominant splicing variant of Factor VII in normal liver corresponds to the 444 amino acid precursor (3, 4). After a signal peptide (residues 1 to 38), the mature chain can be further processed into the light chain (residues 39 to 190) and the heavy chain (residues 191 to 444). The purified Recombinant Human Factor VII corresponds to the mature chain, which can be processed and activated by treatment with thermolysin and binding with Recombinant Human Coagulation Factor III/Tissue Factor (Catalog # http://www.rndsystems.com/product_results.aspx?k=2339-PA">2339-PA) under the conditions described above.
