Recombinant Mouse Coagulation Factor VII Protein, CF

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 deduced amino acid sequence of mouse factor VII predicts a signal peptide (residues 1 to 24), propeptide (residues 25 to 41), and the mature chain that can be further processed into the light chain (residues 42 to 193) and the heavy chain (residues 194 to 446). The purified recombinant mouse F7 corresponds to the mature chain, which can be processed and activated by treatment with thermolysin and binding with recombinant mouse Tissue Factor (Catalog # http://www.rndsystems.com/product_results.aspx?k=3178-PA">3178-PA) under the conditions described in the Activity Assay Protocol.
