Description
Factor V Polyclonal Antibody – Affinity Purified
Affinity’s Factor V Polyclonal Antibody – Affinity Purified is the highest level of our Factor V antibody family. 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 is provided in a solution of HEPES buffered saline containing 50% glycerol (v/v) and is intended for applications such as immunoblotting, immunostaining of cells and several types of immunoassays where the higher signal-to-noise ratio achieved with this enriched product is required.

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 is located on chromosome 1. A congenital deficiency of factor V is a hemorrhagic disorder inherited as an autosomal recessive disease. The concentration of factor V in plasma is typically 10 μg/mL. Factor V 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 factor V to FVa. Thrombin also acts to down-regulate FVa indirectly by activating Protein C, which inactivates FVa cofactor activity1-3.
