Thrombin-like snake venom serine protease that clots fibrinogen by releasing fibrinopeptide A. According to PubMed:8585090, only cleaves rabbit fibrinogen, whereas no specificity is described in PubMed:3910643. Also acts as a C3 convertase that independently cleaves human C3 and kick-starts the complement cascade. Also increases urokinase-type plasminogen activator and plasminogen activator inhibitor in cultured bovine pulmonary artery endothelial cells. Dose-dependently inhibits collagen-induced platelet aggregation.

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
