Product Overview
This rabbit polyclonal antibody detects antithrombin-III (gene SERPINC1) in human, mouse and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 52.6 kDa, and the supplier reports an observed band at about 53 kDa.
Antithrombin-III (antithrombin, SERPINC1) is the main plasma serpin that controls blood coagulation. It inactivates thrombin and factors IXa, Xa and XIa, and its activity is strongly accelerated by heparin, which is the basis of heparin's anticoagulant effect; inherited antithrombin deficiency increases the risk of venous thrombosis.

Immunogen
Recombinant human Antithrombin III/SERPINC1 fragment (Arg89–Lys464), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes antithrombin-III as a secreted protein. Tissue expression noted by UniProt (human): Found in plasma. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
