Human Coagulation Factor VII Antibody Summary
Accession # NP_062562
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Human Coagulation Factor VII by Western Blot. Western blot shows human plasma and lysate of human liver tissue. PVDF membrane was probed with 2 µg/mL of Goat Anti-Human Coagulation Factor VII Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2338) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Coagulation Factor VII at approximately 50-55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Coagulation Factor VII in human PBMCs. Coagulation Factor VII was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Goat Anti-Human Coagulation Factor VII Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2338) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

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 1-38), the mature chain can be further processed into the light chain (residues 39-190) and the heavy chain (residues 191-444). The purified rhFactor VII corresponds to the mature chain, which can be processed and activated by treatment with thermolysin and binding with recombinant human Tissue Factor (R&D Systems, Catalog # 2339-PA) under the conditions described above.
