• Product name

  • Description

    Rabbit polyclonal to Factor V
  • Host species

  • Tested applications

    Suitable for: Double Immunodiffusion, Immunodiffusion, IPmore details
  • Species reactivity

    Reacts with: Human
  • Immunogen

    Full length native protein (purified) corresponding to Human Factor V. (Isolated from pooled human plasma).
    Database link: P12259

  • Positive control

    • Human plasma.
  • General notes

    Measured by quantitative precipitin analysis the amount of Factor V precipitated by 1 ml antiserum is between 8 and 12 U. One Unit of Factor V is defined as the amount of Factor V present in 1 ml normal plasma. On average this corresponds to 20 μg.


  • Form

    Lyophilised:Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the antiserum.
  • Storage instructions

    Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C long term. Avoid freeze / thaw cycle.
  • Storage buffer

    Preservative: 0.1% Sodium azide

    No foreign proteins added.
  • Concentration information loading...
  • Purity

    Whole antiserum
  • Purification notes

    Delipidated, heat inactivated, stable whole antiserum, dialyzed against glycine buffer. Total protein and IgG concentrations in ab182958 are comparable to those of pooled normal rabbit serum.

Our Abpromise guarantee covers the use of ab182958 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Double Immunodiffusion Use at an assay dependent concentration.

In double radial immunodiffusion use a rosette arrangement with 10 μl antiserum in 3 mm diameter center well and 2 μl plasma samples (neat and serially diluted) in 2 mm diameter peripheral wells.

Immunodiffusion Use at an assay dependent concentration.

In electroimmunodiffusion the antiserum concentration required in the gel is normally between 1 and 2%.

IP Use at an assay dependent concentration.


  • Function

    Central 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.
  • Tissue specificity

  • Involvement in disease

    Factor V deficiency
    Thrombophilia due to activated protein C resistance
    Budd-Chiari syndrome
    Ischemic stroke
    Pregnancy loss, recurrent, 1
  • Sequence similarities

    Belongs to the multicopper oxidase family.
    Contains 3 F5/8 type A domains.
    Contains 2 F5/8 type C domains.
    Contains 6 plastocyanin-like domains.
  • Domain

    Domain B contains 35 x 9 AA tandem repeats, and 2 x 17 AA repeats.
  • Post-translational

    Thrombin 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.
