The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 5 µg/ml.
Use at an assay dependent dilution. RID: 6 ul antiserum/cm2 gel vs. 5 ul neat -1:10 dilution human plasma.
Use at an assay dependent dilution. 100 ul antiserum vs. 5 ul plasma gives single arc. Note: The use of 3% PEG 6000 with 1.2% agarose in a suitable buffer (such as TBE or Tris-barbital pH >8.2) is recommended.
Use at an assay dependent dilution. 10 ul antiserum vs. 5 ul plasma.
FunctionMost important serine protease inhibitor in plasma that regulates the blood coagulation cascade. AT-III inhibits thrombin as well as factors IXa, Xa and XIa. Its inhibitory activity is greatly enhanced in the presence of heparin.
Tissue specificityFound in plasma.
Involvement in diseaseDefects in SERPINC1 are the cause of antithrombin III deficiency (AT3D) [MIM:613118]. AT3D is an important risk factor for hereditary thrombophilia, a hemostatic disorder characterized by a tendency to recurrent thrombosis. AT3D is classified into 4 types. Type I: characterized by a 50% decrease in antigenic and functional levels. Type II: has defects affecting the thrombin-binding domain. Type III: alteration of the heparin-binding domain. Plasma AT-III antigen levels are normal in type II and III. Type IV: consists of miscellaneous group of unclassifiable mutations.
Sequence similaritiesBelongs to the serpin family.
Post-translational modificationsPhosphorylation sites are present in the extracelllular medium.
