  • FunctionFactor VIII, along with calcium and phospholipid, acts as a cofactor for factor IXa when it converts factor X to the activated form, factor Xa.
  • Involvement in diseaseDefects in F8 are the cause of hemophilia A (HEMA) [MIM:306700]. A disorder of blood coagulation characterized by a permanent tendency to hemorrhage. About 50% of patients have severe hemophilia resulting in frequent spontaneous bleeding into joints, muscles and internal organs. Less severe forms are characterized by bleeding after trauma or surgery. Note=Of particular interest for the understanding of the function of F8 is the category of CRM (cross-reacting material) positive patients (approximately 5%) that have considerable amount of F8 in their plasma (at least 30% of normal), but the protein is non-functional; i.e., the F8 activity is much less than the plasma protein level. CRM-reduced is another category of patients in which the F8C antigen and activity are reduced to approximately the same level. Most mutations are CRM negative, and probably affect the folding and stability of the protein.
  • 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 F5/8 type C 2 is responsible for phospholipid-binding and essential for factor VIII activity.
  • Post-translational
    Sulfation on Tyr-1699 is essential for binding vWF.

We have not previously used this antibody in rat and so we cannot guarantee that it will work.

I have compared the total homology with rat and there is 46% homology due to some parts of the protein being very well conserved and others which ha...

Thank you for your inquiry.
This polyclonal must be able to bind FVIII/vWF complex in plasma since it is inhibitory.
However, I do not know if can bind the complex in a western blot application. This hasn't been tested, unfortunately.
I ...

Thank you for contacting Abcam.

I do not think that you would be able to use the same antibody as both the capture and detection antibody in your sandwich ELISA, as you would want each antibody to detect different portions of the protein.
