Our Abpromise guarantee covers the use of ab124259 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 5 µg/ml.
Immunodiffusion Use at an assay dependent dilution. RID: 6 ul antiserum/cm2 gel vs. 5 ul neat -1:10 dilution human plasma.
Immunoelectrophoresis 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.
Double Immunodiffusion Use at an assay dependent dilution. 10 ul antiserum vs. 5 ul plasma.


  • Function

    Most 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 specificity

    Found in plasma.
  • Involvement in disease

    Defects 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 similarities

    Belongs to the serpin family.
  • Post-translational

    Phosphorylation sites are present in the extracelllular medium.
  • Cellular localization

    Secreted > extracellular space.
