General description
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.
Specificity
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.
Immunogen
Factor VII from pooled normal human plasma.
Application
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.
Biochem/physiol Actions
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 VIIa, by Factor Xa, Factor IXa, thrombin and Factor XIIa or β XIIa.
Physical form

We report here a new method for the alternative peptide tagging of recombinant proteins from mammalian cell lines. This method, which we called regulated readthrough, exploits the property of aminoglycoside antibiotics to promote translational readthrough of nonsense codons. The basic

We report the development of an enzyme-linked immunosorbent assay (ELISA) that is specific for factor VIIa (FVIIa). This assay uses a neoantigen specific capture antibody directed to the amino acid peptide sequence N terminal to the FVII cleavage activation site.
