Product details

Abcam's Factor VII Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Factor VII concentrations in Human serum and plasma.

A Factor VII specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Factor VII specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of Factor VII captured in plate. This assay recognizes FVII and FVIIa.

Get higher sensitivity in only 90 minutes with Human Factor VII ELISA Kit (ab190810) from our SimpleStep ELISA® range.

The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

Factor VII also known as factor 7 or factor seven is a plasma glycoprotein with a molecular mass of approximately 50 kDa. It plays an important role in the blood coagulation process. Factor VII is mainly produced in the liver and requires vitamin K for its synthesis. In the inactive form it circulates in the plasma but upon activation to factor 7a it initiates the extrinsic pathway of blood coagulation. This activation is a critical step in hemostasis which helps to prevent excessive bleeding.
Biological function summary

Factor 7a indirectly activates further components in the blood coagulation cascade. Upon activation factor 7a becomes a part of the tissue factor (TF) complex which includes tissue factor expressed on subendothelial cells. The complex triggers the activation of factor IX and factor X propagating the coagulation cascade downstream. This series of activations amplifies the signal for clot formation highlighting factor VII's integral role in initiating coagulation.

Pathways

Factor VII is primarily involved in the extrinsic pathway of the coagulation cascade. This pathway is initiated when factor 7a forms a complex with tissue factor a protein that becomes exposed at injury sites. Factor VII is also indirectly linked to the common coagulation pathway through activation of factor X. The interaction between these pathways ensures efficient and rapid clot formation. Additionally factor IX also interacts with factor VII in the intricate network of coagulation processes that sustain hemostasis.

Deficiencies or dysfunctions in factor VII can lead to coagulopathies such as congenital factor VII deficiency which results in excessively prolonged bleeding. Conversely elevated factor VII activity can contribute to thromboembolic disorders like myocardial infarction. In these conditions factor VII often interacts with proteins like factor X and tissue factor highlighting their clinical significance in managing blood coagulation abnormalities.

Product protocols

Target data

Initiates the extrinsic pathway of blood coagulation. Serine protease that circulates in the blood in a zymogen form. Factor VII is converted to factor VIIa by factor Xa, factor XIIa, factor IXa, or thrombin by minor proteolysis. In the presence of tissue factor and calcium ions, factor VIIa then converts factor X to factor Xa by limited proteolysis. Factor VIIa will also convert factor IX to factor IXa in the presence of tissue factor and calcium.
