Technical Data
Antithrombin III (ATIII)
Antithrombin III (ATH III) is a plasma protein synthesized in the liver. Normal plasma levels are 115 to 160mg/L. ATH III consists of a single polypeptide chain and has a molecular weight of 58kDa. ATH III is a serine protease inhibitor and regulates coagulation by the formation of covalently liked complexes. ATH III also has a heparin binding site and in the presence of heparin the inhibition of thrombin, factors IXa, Xa and XIa is enhanced 1000 fold. Low levels of ATH III (functional or concentration) are associated with deep vein thrombosis and pulmonary embolism. Antithrombin assays are based on immunologic, enzymatic, or clotting properties

Suitable for use in RID, Double Difffusion and Rocket IEP. Other applications not tested.

Recommended Dilutions:
RID: Neat-1:10; 6ul antiserum/cm2 in gel vs 5ul fresh plasma
Double Diffusion: 10ul antiserum vs 5ul fresh plasma
IEP: 100ul antiserum vs 5ul fresh plasma
Note: Use 3% PEG 6000 with 1.2% agarose in a suitable buffer (TBE or Tris-barbital pH > 8.2).
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Human antithrombin III purified from plasma. Cellular Localization: Secreted protein; extracellular space.
Supplied as a liquid in GBS, pH 7.4, 0.1% EACA, 0.01% benzamidine,1mM EDTA, 0.099% sodium azide.
Recognizes human antithrombin III. A single arc is detected when tested by IEP and 2D-IEP against human plasma. Identity is confirmed by double diffusion (Ouchterlony) vs human plasma and a known anti-human antithrombin III. Species Crossreactivity: rat, equine, mouse, canine and feline. Does not react with rabbit, bovine, porcine, guinea pig or chicken.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
