DescriptionATIII – Antithrombin Polyclonal Antibody – GoatAffinity’s ATIII – Antithrombin Polyclonal Antibody – Goat is the base level of our ATIII – Antithrombin antibody family. The purity of IgG is typically 90% and is provided in a solution of HEPES buffered saline containing 50% glycerol (v/v). The titre is essentially the same as the starting antiserum and each vial typically contains the amount of IgG recovered from one milliliter of antiserum. This ATIII – Antithrombin Polyclonal Antibody – Goat is generally intended for use in applications such as immuno-precipitation, immuno-electrophoresis, immuno-depletion and activity neutralization assays.Product Code: GAAT-IGRetail Product Size: 10mg vialHost Animal: Goat Anti-Human ATIII – Antithrombin Polyclonal Antibody – GoatSpecies Cross Reactivity: View ChartProduct Datasheet: Antithrombin ATIII Polyclonal Antibody, purified anti-human goat IgGDescription of AntithrombinAntithrombin, also known as Antithrombin III (ATIII), is a member of the SERPIN family of proteinase inhibitors and the primary inhibitor of thrombin in plasma. It is produced in the liver and circulates in plasma at ~200 μg/ml (~3.5 μM). Antithrombin inhibits a broad spectrum of serine proteases including thrombin, activated forms of factor X, factor IX, factor XI, factor XII, as well as kallikrein, plasmin and urokinase. Enzyme inhibition by antithrombin occurs through proteolytic cleavage at Arg385-Ser386 and subsequent rapid formation of a stable, inactive 1:1 enzyme-antithrombin complex. Heparin has a profound accelerating effect on the inhibitory activity of antithrombin towards some enzymes. For example, the rate of inhibition of thrombin and activated factor X is increased 1000-fold in the presence of optimal concentrations of heparin, whereas heparin has relatively little effect on the inhibition rate of activated factor XI, activated factor XII and kallikrein. Antithrombin is a single chain molecule with a molecular weight of 59 kDa. Interaction with thrombin results in an SDS-stable thrombin-antithrombin complex of 96 kDa1-3.References and ReviewsDamus PS, Rosenberg RD; Antithrombin – Heparin Cofactor; Methods in Enzymology 45, pp 653-669, 1976.Harpel PC; Blood Proteolytic Enzyme Inhibitors: Their Role in Modulating Blood Coagulation and Fibrinolytic Enzyme Pathways; in Hemostasis and Thrombosis, eds.
