Product Synonym Names
Thrombin, bovine
Research Use Only
For Research Use Only. Not for use in diagnostic procedures.
Prior to conjugation, this antibody was specific for bovine thrombin or prothrombin as demonstrated by immunoelectrophoresis and ELISA.
Peroxidase conjugated IgG.
Vial containing 1mg/ml of whole IgG conjugated to horseradish peroxidase (HRP) through carbohydrate groups. Total protein is 0.2 mg.
IgG-HRP conjugate as a clear, slightly red-brown liquid.
IgG-HRP concentration is 2mg/ml, determined by absorbance using an extinction coefficient (E1%280) of 14. (lot specific)
Thrombin prepared from purified bovine prothrombin, active site blocked with PPACK.
Rz Ratio (Reinheitszahl, A403/A280)
0.49 as determined spectrophotometrically.
A buffered stabilizer solution containing 50% (v/v) glycerol.
Preparation and Storage
Store between -10 and -20 degree C. Product will become viscous but will not freeze. Avoid storage in frost-free freezers. Keep vial tightly capped. Allow product to warm to room temperature and gently mix before use. Avoid exposure to sodium azide as this is an inhibitor of peroxidase activity.
Other Notes
Small volumes of anti-Thrombin antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
anti-Thrombin antibody
Thrombin (EC3.4.21.5, alpha-thrombin) is the product of proteolytic activation of the zymogen prothrombin. Human thrombin is a two-chain serine protease with a mass of 37 kDa. The active site is located within the heavy chain. Thrombin has a high specificity for certain arginine bonds in protein substrates. The primary substrate is fibrinogen which thrombin converts to fibrin through the cleavage of four arginyl-glycyl peptide bonds. Thrombin is also an important activator of platelets, factor XIII, Protein C and TAFI (Plasma procarboxypeptidase B). In a positive feedback mechanism, thrombin increases the rate of its own production by activation of factors VIII and V. The rate of thrombin production is subsequently limited indirectly through the activation of Protein C by thrombin, which then inactivates the activated cofactors VIII and V. The binding of thrombin to thrombomodulin on the cell surface dramatically alters thrombin's specificity, increasing it's activity toward Protein C and TAFI, and decreasing it's activity toward fibrinogen and activating cofactors VIII and V. In plasma, thrombin activity is inhibited primarily by antithrombin and to a lesser extent heparin cofactor II. The rate of inhibition by both of these inhibitors is profoundly increased in the presence of optimal concentrations of heparin. Other physiological inhibitors of thrombin in the absence of heparin include alpha2-macroglobulin and alpha1-antitrypsin1-4.
