Coagulation Factor VII in Human PBMCs.
Coagulation Factor VII was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Human Coagulation Factor VII Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF2338) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Streptavidin (yellow; Catalog # NL999) and counterstained with DAPI (blue).

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 39-190) and the heavy chain (residues 191-444).
