Tissue-type plasminogen activator (tPA) circulating in plasma exists in free forms as well as in tPA-inhibitor complexes. The underlying biochemical mechanism governing coagulation and fibrinolysis involves a controlled cascade of proteolytic reactions characterized by the conversion of serine protease zymogens to enzymes. Depending upon the initiating stimulus, the physiological outcome of these reactions is blood clot formation/dissolution. The relative concentrations of serine protease zymogen, enzyme, or enzyme-inhibitor complex in circulation will vary in accord with the state of vascular damage. Many conventional antigen-based clotting factor-specific immunoassays do not distinguish between zymogen and enzyme. Applications: Suitable for use in ELISA, Immunohistochemistry and Western Blot. Other applications not tested. Recommended Dilutions: ELISA: 1:10,000-1:100,000 Western Blot: 1:1000-1:10,000 Immunohistochemistry (Frozen, paraformaldehyde-fixed): 1:100-1:1000 Optimal dilutions to be determined by the researcher.
