Factor V Polyclonal Antibody – Affinity Purified – Biotinylated
Affinity’s Factor V Polyclonal Antibody – Affinity Purified – Biotinylated is the highest level of our biotin conjugated Factor V antibodies. During the Antigen Affinity Purification process the IgG has had any non-specific immunoglobulin fraction eliminated which enriches the specificity of the remaining immunoglobulin towards the target antigen. The result is a very high-purity product with a substantially higher titre than whole or purified IgG. Our Factor V Polyclonal Antibody – Affinity Purified – Biotinylated is provided in a solution of HEPES buffered saline containing 50% glycerol (v/v) and has been conjugated with Biotin as an enzyme reporter. This antibody is generally intended for use as labelled primary antibodies in applications such as immunoassay and immunoblotting.

Description of Factor V
Factor V (formerly referred to as accelerator globulin and labile factor) is a large glycoprotein (320 kDa) that is produced in the liver. The gene that encodes factor V (FV) is located on chromosome 1. A congenital deficiency of FV is a hemorrhagic disorder inherited as an autosomal recessive disease. The concentration of FV in plasma is typically 10 μg/mL. FV is a pro-cofactor that is activated through limited proteolysis by thrombin, or by activated factor X in the presence of phospholipid surface. Other physiologic activators of FV include plasmin, neutrophil elastase and platelet calpain. The activated cofactor (FVa) is an essential component of the prothrombin activator complex, which consists of FVa, activated factor X, calcium and anionic phospholipid surface. The intact prothrombinase complex activates prothrombin to thrombin at a rate 300,000-fold greater than activated factor X alone. In a positive feedback loop, the thrombin generated accelerates its own generation by activating more FV to FVa. Thrombin also acts to down-regulate FVa indirectly by activating Protein C, which inactivates FVa cofactor activity1-3.
