特徴

• Apolipoprotein-H, also known as beta2-Glycoprotein I (beta2GPI), is a plasma glycoprotein that circulates at a concentration of 200ug/ml (4uM).
• Synthesized in the liver, beta2GPI is a single chain molecule of 48kD, consisting of five repeating internally disulphide-bonded structures referred to as sushi domains.
• Relative to other glycoproteins, beta2GPI has an unusually high content of cysteine (6.2%), proline (8.3%) and carbohydrate (19%).
• Almost half the circulating b2GPI in plasma is associated with lipoproteins of all major fractions.
• beta2GPI has been demonstrated to bind negatively charged phospholipids, heparin and platelets.
• Although the precise function(s) are as yet unknown, beta2GPI has been demonstrated to interfere with blood coagulation by competitively binding to negatively charged phospholipid surfaces exposed during cell activation or damage.
• Recent evidence also implicates beta2GPI as a cofactor recognized by anti-phospholipid antibodies present in some autoimmune disorders such as systemic lupus erythematosus (SLE).
• Applications:Suitable for use in ELISA, Immunodiffusion and Immunoelectrophoresis.
• Other applications not tested.
• Recommended Dilutions:Optimal dilutions to be determined by the researcher.
