Human Serpin A5/Protein C Inhibitor Antibody

Serpin A5 is the a member of the Serpin superfamily and inhibits a variety of serine proteases such as protein C, plasminogen activators, thrombin, factor Xa, several kallekreins and acrosin (1). Serpin A5 is synthesized in the liver and secreted in plasma. It is found in numerous steroid-responsive organs and has been detected in saliva, cerebral spinal fluid, amniotic fluid, tears and semen. Because of its protease targets and regulated expression patterns, Serpin A5 has been proposed to play a role in processes such as blood coagulation, fertilization and carcinogenesis (2, 3). Similar to Serpins C1 and D1, its thrombin inhibitory activity is enhanced by heparin.
