Anti-Factor VII antibody, Mouse monoclonal

Anti-Factor VII antibody, mouse monoclonal (mouse) IgG1 isotype) is derived from the HVII-1 hybridoma produced by the fusion of mouse Sp2/0-Ag14 myeloma cells and splenocytes from immunized BAB/c mice. Human coagulation factor VII contains 10 gamma-carboxyglutamic acid residues (Gla), located at the N-terminal region of the molecule. The activated factor VII (factor VIIa) also consists of a light chain with the Gla-domain and an epidermal growth factor domain, which is linked by a disulfide bond to a heavy chain, containing the serine protease catalytic domain.

Factor VII from pooled normal human plasma.

Anti-Factor VII antibody, Mouse monoclonal has been used in:

• the preparation of factor VII - depleted plasma and for purification
• sandwich-type immunoassays
• the evaluation of patients with hereditary factor VII deficiency by an enzyme linked immunosorbent assay (ELISA) or radio immunosorbent assay (RIA)
• the assay of factor VII level in patients with liver disease (a sensitive parameter of liver dysfunction)
• epidemiological studies of the importance of factor VII level as a risk factor for coronary heart disease, cerebrovascular disease and peripheral vascular diseases
• the determination of the activity state of factor VII in in vivo samples when used with a clotting assay
• flow cytometry

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Flow cytometry/Cell sorting (1 paper)

Monoclonal Anti-Factor VII antibody is suitable for flow cytometry analysis to study the behavior of TF-fVIIa secreted by ovarian cancer cells was associated with microparticles (MPs). It is also suitable for western blot at a dilution of 1:4,000 and indirect ELISA.

Factor VII is a single-chain vitamin K-dependent glycoprotein in human coagulation. It has a molecular weight of ∼50,000Da, present in plasma in trace quantities. It is predominantly synthesized in liver and depends on the posttranslational γ−carboxylation of specific glutamic residues located near the NH2-terminus of the molecule. It is a serine protease zymogen and for activation it requires proteolytic cleavage in the disulfide-linked, two-chain form, Factor VII_a, by Factor X_a, Factor IX_a, thrombin and Factor XII_a or β XII_a.

The antibody recognizes an epitope on the light chain of Factor VII in the presence or absence of divalent cations. Clone no. HVII-1 (also cited as clone no. MC1476/E.A.8.1) may be used for purification of Factor VII and for the preparation of Factor VII depleted human plasma.
