Our Abpromise guarantee covers the use of ab95077 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
2ml of 1:1 slurry
1.0 mg/ml coupled
May be used repeatedly. Protocol for purifying high affinity heparin with immobilized antithrombin:
1. Equilibrate immobilized antithrombin in TBS (0.1M Tris-HCl, 0.15M NaCl, pH 7.4) or PBS (0.05M Sodium Phosphate, 0.15M NaCl, pH 7.4).
2. Apply heparin in TBS or PBS. Binding capacity is ~0.1 mg high affinity heparin / ml resin and must be determined by the end user.
3. Wash and elute heparin with 3M NaCl in TBS or PBS.
4. Re-equilabrate resin in TBS or PBS.
5. Add 0.02percent Sodium Azide for storage.

- Antithrombin III
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.
modificationsPhosphorylation sites are present in the extracelllular medium.
Cellular localizationSecreted > extracellular space.
