Abcam’s Factor V Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Factor V in plasma, urine, milk, and cell culture supernatants.
A Factor V specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Factor V 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 V captured in plate.
The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.
Storage instructionsStore at -20°C. Please refer to protocols.

FunctionCentral regulator of hemostasis. It serves as a critical cofactor for the prothrombinase activity of factor Xa that results in the activation of prothrombin to thrombin.
Involvement in diseaseFactor V deficiency
Thrombophilia due to activated protein C resistance
Pregnancy loss, recurrent, 1
Sequence similaritiesBelongs to the multicopper oxidase family.
Contains 3 F5/8 type A domains.
Contains 2 F5/8 type C domains.
Contains 6 plastocyanin-like domains.
DomainDomain B contains 35 x 9 AA tandem repeats, and 2 x 17 AA repeats.
modificationsThrombin activates factor V proteolytically to the active cofactor, factor Va (formation of a heavy chain at the N-terminus and a light chain at the C-terminus).
Sulfation is required for efficient thrombin cleavage and activation and for full procoagulant activity.
Activated protein C inactivates factor V and factor Va by proteolytic degradation.
Phosphorylation sites are present in the extracellular medium.
